Best Hiking Fleeces: 12 Top Midlayers For UK Trails (2026)

A fleece midlayer earns its place in your pack on almost every UK hike. Whether you're scrambling up Snowdon in April or crossing the Cairngorms in October, the right fleece traps warmth without turning you into a sweaty mess on the uphill. But with dozens of options across different weights, fabrics, and fits, picking the best hiking fleeces comes down to knowing exactly what performs well on real trails in real conditions.

We've pulled together 12 fleeces that genuinely deliver for UK hikers, rated on warmth-to-weight ratio, breathability, durability, and how well they layer under a waterproof shell. From lightweight Polartec options built for fast-paced ridge walks to heavyweight full-zips that double as standalone jackets on dry winter days, there's something here for every season and budget.

At MoreSports, we stock outdoor gear from brands like Craghoppers and Berghaus across our online store and our shop in Coleraine, Northern Ireland. We've used that hands-on product knowledge to put this guide together, so you can pick the right fleece and get straight to the trail.

1. MoreSports: how to choose and buy the right fleece

Before diving into the best hiking fleeces on the market, it helps to understand what separates a fleece that looks good on paper from one that actually works for you on UK trails. The right choice depends on where you hike, how hard you push, and how you plan to layer across different conditions and seasons.

What a hiking fleece needs to handle in the UK

UK weather rarely sits still. You can start a walk in Snowdonia under clear skies and find yourself in horizontal rain and wind an hour later. A hiking fleece needs to manage moisture when you're working hard and retain warmth the moment you stop. Wind resistance matters too - open-knit fleeces that breathe brilliantly on the ascent can feel cold the second a breeze picks up on the ridge.

The UK's unpredictable weather means your fleece needs to perform both on the move and at rest, not just in one scenario.

How to pick the right warmth and weight

Fleece weight falls into three broad categories. Lightweight fleeces (around 100g/m²) suit aerobic hiking and shoulder-season use when you run warm. Midweight fleeces (200g/m²) work as a true midlayer across most UK seasons and most hikers' needs. Heavyweight options (300g/m²+) double as standalone jackets on cold, dry days but can overheat on sustained climbs.

Weight	Best use	Season
Lightweight (~100g/m²)	Fast hiking, high-output days	Spring/Summer
Midweight (~200g/m²)	All-day hiking, reliable midlayer	Year-round
Heavyweight (~300g/m²+)	Cold stops, standalone jacket	Autumn/Winter

How to choose fabric and fleece type

Polartec Classic and Power Stretch remain the benchmark for stretch and moisture management in performance fleeces. Recycled polyester options from brands like Craghoppers and Patagonia now match that performance while reducing environmental impact. Grid fleece fabrics trap more air per gram than flat-knit options, making them efficient for their weight. If wind is a regular factor on your routes, look for bonded panels or a tighter face fabric rather than a fully open construction.

Fit and layering checklist for UK conditions

Fit directly affects how well your fleece layers under a waterproof shell. A fleece that bunches at the sleeves or pulls across the shoulders will compromise your waterproof jacket's fit and your freedom of movement. Run through this checklist before you commit to a size:

• Sleeves reach your wrist with your arms raised
• No excess fabric across the back when a shell sits over the top
• Hem drops below your waistband to prevent cold gaps
• Collar doesn't push up uncomfortably under a shell hood
• Articulated elbows allow full arm movement without resistance

Buying checklist: delivery, returns and sizing

MoreSports provides free UK delivery on orders over £25 and 90-day returns on unused items, which removes the risk from ordering a size you're uncertain about. Most fleece brands run true to size, but grid fleeces with a stretch construction can allow you to size down for a closer, more athletic fit under a shell. Always check the brand size guide before ordering - there is a noticeable difference between a Patagonia medium and a Craghoppers medium in the chest and sleeve measurements.

2. Patagonia R1 Air Full-Zip Hoody

The Patagonia R1 Air Full-Zip Hoody is built for high-output hiking where moisture management matters more than raw warmth. Its Polartec Power Air fabric traps air in internal cells rather than external loops, making it exceptionally breathable while significantly reducing microfibre shedding in the wash.

Why it suits UK hiking

UK ascents generate heat fast, and the R1 Air handles that well. The open-cell fabric construction dumps excess body heat efficiently on steep ground, keeping you comfortable without forcing a stop to adjust layers. The full-zip design adds precise ventilation control that you can manage on the move.

The attached hood gives you protection from light wind and drizzle on exposed sections without adding bulk beneath a waterproof shell.

Warmth, breathability and wind performance

This fleece sits firmly in the lightweight, high-breathability category rather than the warmth category. At aerobic pace it performs very well, but the open construction offers minimal wind resistance on ridges and summits, so pair it with a windproof shell on any exposed terrain.

Treat the R1 Air as a high-performance active layer rather than a standalone warmth piece and it will rarely let you down.

Fit, comfort and layering

Patagonia cuts this fleece slim through the torso and arms, which makes it an excellent choice under a waterproof jacket without creating unwanted bulk. The articulated patterning allows full arm movement on steep or technical ground without the fabric pulling across the back or shoulders.

Features that matter on the hill

Key features worth noting:

• Low-profile hood sits cleanly under a shell or helmet without adding collar bulk
• Full-zip runs hem to chin with no snagging on baselayer collars
• Hem drops below the waistband when your arms are raised
• Built with recycled content for a reduced environmental footprint

Price and value

At around £150-£160, the R1 Air sits at the premium end of the fleece market. For fast-paced, high-output hiking days, that price reflects genuine fabric innovation and long-term durability. If you hike at a steadier pace or tend to run cold, a midweight fleece will serve you better at a lower price point.

3. Rab Evolute Hoody

The Rab Evolute Hoody is one of the best hiking fleeces built around Polartec Power Stretch Pro, a fabric that combines four-way stretch with efficient moisture transfer to keep you comfortable across a wide range of hiking intensities. Rab's construction and attention to technical detail make this a fleece that performs well beyond its price point.

Why it suits UK hiking

UK conditions swing between wet, sweaty ascents and cold, exposed ridgelines within the same walk. The Evolute handles both ends of that range with confidence. Polartec Power Stretch Pro moves moisture away from your skin on hard climbs while retaining enough warmth to keep you comfortable the moment you stop at a summit or viewpoint.

Warmth, breathability and temperature control

The Evolute sits at the lighter end of midweight fleeces, which makes it a versatile choice across spring, summer, and autumn hiking across UK trails. Its close-knit outer face resists wind penetration more effectively than open-grid constructions, which gives you noticeably more comfort on exposed ridgelines and cols where open-knit fleeces fall short.

Treat the Evolute as a high-output midlayer rather than a standalone warmth piece, and pair it with a windproof shell on any exposed ground above 600 metres.

Fit, comfort and layering

Rab cuts the Evolute with a trim, athletic profile that sits close to the body without restricting arm or shoulder movement. That close fit makes it ideal under a waterproof jacket, with minimal excess fabric bunching at the back or shoulders when you pull a shell over the top. Thumb loops keep the sleeves in place under gloves during cold early starts.

Features that matter on the hill

• Polartec Power Stretch Pro face resists abrasion from rucksack straps and harnesses
• Low-profile hood sits cleanly under a shell helmet without adding collar bulk
• Chest zip pocket doubles as a pack-away pouch for easy stowing

Price and value

At around £120-£130, the Evolute delivers solid value for a technical Power Stretch fleece. Rab's build quality holds up well across multiple seasons of regular use, making the long-term cost per wear competitive against cheaper options that lose their stretch and moisture-management performance after heavy use.

4. Craghoppers CO2 Renu Half Zip Fleece

The Craghoppers CO2 Renu Half Zip Fleece stands out among the best hiking fleeces for anyone who wants reliable midlayer performance and a lower environmental footprint without paying a premium price. Craghoppers constructs this fleece from recycled CO2 Renu polyester, which captures carbon emissions during manufacturing rather than relying on virgin materials.

Why it suits UK hiking

UK trails demand a fleece that handles variable temperatures and wet conditions across a single day out. The CO2 Renu half-zip design gives you quick ventilation control when you're working hard on a steep ascent, and the high collar with half-zip closure seals out wind efficiently when you stop at a summit or exposed viewpoint.

This makes it a particularly practical choice for walkers who prefer not to carry an extra shell layer on milder UK autumn days.

Warmth and breathability in real use

The fabric sits in the midweight category, delivering enough warmth for cool spring mornings and autumn afternoons on the hills without overheating on steady climbs. Craghoppers uses a brushed inner face that feels soft against a baselayer and traps warm air efficiently without adding unnecessary weight to your pack.

Fit, comfort and layering

Craghoppers cuts the CO2 Renu with a relaxed, regular fit that works well for walkers who prefer some room to move without a close athletic profile. The sleeves carry enough length to cover your wrists when your arms are raised, and the hem drops to the hip to prevent cold gaps above your waistband on uphill sections.

Features that matter on the hill

• Half-zip collar provides fast, precise temperature regulation without removing the fleece
• Two zip hand pockets give secure storage for a phone, snacks, or a map
• Made from recycled CO2 Renu polyester, reducing the carbon footprint versus standard fleece fabrics
• Lightweight enough to compress into a rucksack side pocket as a backup layer

Price and value

At around £50-£60, the CO2 Renu sits well below the premium end of the fleece market. For walkers who hike regularly across UK seasons and want a durable midweight option from a trusted outdoor brand, this represents strong value for money.

5. Montane Fury Lite Hooded Fleece Jacket

The Montane Fury Lite Hooded Fleece Jacket earns its place among the best hiking fleeces for UK conditions through a combination of lightweight construction and fast-drying Polartec Power Stretch Pro that suits the wet, changeable weather you regularly encounter across British mountains. Montane has a long track record building technical kit for UK hillwalkers, and the Fury Lite reflects that experience clearly.

Why it suits UK hiking

UK trails produce sustained climbs followed by sudden cold stops at summits, and the Fury Lite handles that transition better than most fleeces in this weight bracket. The Power Stretch Pro fabric moves moisture away from your skin efficiently on hard aerobic sections, then retains enough warmth to keep you comfortable during rest stops without needing you to dig out an extra layer.

This makes it a strong choice for solo hikers who prefer to move fast with a minimal pack.

Warmth, breathability and durability

The Fury Lite sits in the lightweight-to-midweight category, which positions it as a high-breathability active layer rather than a heavy-warmth piece. The abrasion-resistant outer face of Power Stretch Pro holds up well against rucksack straps and rocky scrambles, which matters on rougher UK terrain like the Lake District's ridgelines or the Cairngorms plateau.

Fit, comfort and layering

Montane cuts this fleece with a close, athletic fit that layers cleanly under a waterproof shell without creating bunching across the back or shoulders. Articulated elbows allow full arm movement on steep or technical ground, and thumb loops keep the sleeves in place during cold morning starts when you're wearing gloves over the top.

Features that matter on the hill

• Polartec Power Stretch Pro outer face resists abrasion from harnesses and rucksacks
• Low-profile hood sits flat under a waterproof shell without adding collar bulk
• Single chest zip pocket provides secure storage for small essentials
• Hem and cuffs seal well against wind and drizzle on exposed ground

Price and value

At around £120-£130, the Fury Lite competes directly with the Rab Evolute at a similar price point. For hikers who prioritise durability alongside breathability, the abrasion resistance of the Power Stretch Pro face gives Montane a clear edge on technical, rocky routes.

6. Rab Superflux Hoody

The Rab Superflux Hoody sits near the top of the best hiking fleeces for UK conditions, built around a Polartec Power Stretch Pro construction that handles the full range of British mountain weather without forcing you to compromise between breathability and warmth.

Why it suits UK hiking

UK hillwalking regularly combines hard aerobic ascents with cold, exposed stops at summits, and the Superflux handles that transition well. The stretch-woven outer face resists wind penetration better than open-grid fleeces, which gives you noticeably more protection on ridgelines above 600 metres without needing to layer a windshell on top.

This makes the Superflux a strong choice for hikers who want to reduce the number of layers they carry without sacrificing warmth or comfort at rest.

Warmth, breathability and wind performance

The Superflux sits firmly in the midweight performance category, delivering enough warmth for cool autumn days and early spring starts while moving moisture away from your skin efficiently during sustained climbs. The Power Stretch Pro face fabric limits wind chill far more effectively than softer, open-knit alternatives, so you stay comfortable when the pace drops or the exposure increases.

Fit, comfort and layering

Rab cuts the Superflux with a trim, athletic profile that sits close to the body without restricting shoulder or arm movement. That fit layers cleanly under a waterproof shell jacket, with no excess fabric bunching across the back when you pull a second layer over the top. Thumb loops hold the sleeves in position under gloves on cold morning starts.

Features that matter on the hill

• Polartec Power Stretch Pro outer resists abrasion from rucksack straps on long days out
• Low-profile hood packs flat beneath a waterproof shell hood without adding collar bulk
• Chest zip pocket doubles as a stuff sack for compact storage in a rucksack lid

Price and value

At around £130-£140, the Superflux sits at a competitive price point for a technical Power Stretch Pro fleece. Rab's build quality consistently holds up across multiple seasons of regular use, which makes the long-term cost per wear genuinely strong.

7. The North Face Summit Series Futurefleece

The North Face Summit Series Futurefleece is a technical grid fleece aimed at hikers who push hard in demanding terrain. It uses a proprietary grid construction that the brand developed specifically for high-output alpine and mountain use, placing it firmly in the performance midlayer category rather than the casual fleece market.

Why it suits UK hiking

UK mountain days regularly swing between hard aerobic climbs and cold, exposed ridge walks, and the Futurefleece handles that range comfortably. The grid construction moves moisture efficiently on steep ascents, while the close-fitting hood provides wind protection when the pace drops at summits. It works as a standalone piece on milder UK days and layers cleanly under a waterproof shell when conditions deteriorate.

Warmth to weight and breathability

The Futurefleece sits in the lightweight-to-midweight bracket, making it one of the more breathable options in this guide. Its grid face construction creates internal air pockets that trap warmth efficiently per gram of fabric, so you get useful insulation without the weight penalty of a heavier fleece. On sustained climbs in the Lake District or Brecon Beacons, that warmth-to-weight balance keeps you comfortable without forcing a stop to strip layers.

For high-output hiking across exposed UK terrain, the Futurefleece delivers a level of breathability that thicker midlayers simply cannot match at pace.

Fit, comfort and layering

The North Face cuts this fleece with a slim, performance-oriented profile that sits close to the body and layers cleanly under a shell without bunching across the back. Articulated seam placement across the shoulders and elbows allows full arm movement on technical or steep ground.

Features that matter on the hill

• Low-profile hood sits flat under a shell helmet without lifting the collar
• Chest zip pocket provides secure storage for small essentials
• Cuffs and hem sit close to the body to seal against draughts on exposed ground

Price and value

At around £150-£170, the Futurefleece sits at the premium end of the fleece market. For hikers who regularly cover demanding, high-output routes across UK mountains, that price reflects genuine performance credentials and long-term durability from a trusted technical brand.

8. Fjallraven Abisko Lite Fleece

The Fjallraven Abisko Lite Fleece takes a different approach from the performance-focused options higher up this list of best hiking fleeces. Rather than chasing breathability records or abrasion resistance, Fjallraven builds this fleece around sustainable materials and trail-ready durability that holds up across years of regular use on UK paths and hillsides.

Why it suits UK hiking

UK trail conditions vary significantly between lowland footpaths, upland moorland, and exposed mountain ridges. The Abisko Lite handles that range with a midweight construction that provides genuine warmth on cool days without overheating on moderate climbs. Its brushed fleece interior creates an immediately comfortable feel against a baselayer, which suits long days on multi-day routes in Scotland and Wales where comfort across many hours matters as much as technical performance.

Warmth, breathability and durability

The Abisko Lite uses a recycled polyester fleece fabric that balances warmth with adequate moisture management for steady hiking paces. It sits in the midweight category, which means it performs reliably across autumn and spring conditions in the UK but can feel warm on fast-paced summer ascents. The fabric resists pilling well over time, which matters for hikers who wear their fleece heavily across a full walking season rather than saving it for occasional use.

If you prioritise longevity over raw technical performance, the Abisko Lite delivers durability that genuinely outperforms its modest price point.

Fit, comfort and layering

Fjallraven cuts this fleece with a relaxed, regular fit that works well for walkers who prefer room to move without a close athletic profile. That roomier build means it layers comfortably over a midweight baselayer without feeling tight across the chest or shoulders, though it adds more bulk under a waterproof shell than a closer-fitting technical option would.

Features that matter on the hill

• Two hand pockets with zip closures provide secure storage for gloves and a snack
• High collar seals against wind and drizzle on exposed ground without an attached hood
• Constructed with recycled polyester, reducing the environmental impact of production compared to virgin fabric alternatives

Price and value

At around £80-£90, the Abisko Lite sits in the mid-range price bracket. For walkers who prioritise durability and sustainably sourced materials over cutting-edge technical fabrics, it offers honest, straightforward value without unnecessary complexity.

9. Helly Hansen Versalite Hooded Jacket

The Helly Hansen Versalite Hooded Jacket takes a different route from most fleeces in this list of best hiking fleeces. Rather than using a traditional knitted fleece fabric, Helly Hansen builds this jacket around a woven stretch softshell construction that bridges the gap between a midlayer and a light windproof shell, making it a genuinely versatile piece for variable UK conditions.

Why it suits UK hiking

UK mountain weather frequently shifts between light rain, wind, and warm spells within a single day, and the Versalite handles that range comfortably. Its woven face fabric blocks wind and resists light precipitation far more effectively than an open-grid fleece, giving you protection on exposed ridgelines without needing to pull a full waterproof shell over the top on milder days.

This makes it a particularly strong choice for spring and autumn hiking in exposed upland areas like the Cairngorms or the Brecon Beacons, where conditions shift quickly and extra layers add up fast.

Warmth, breathability and wind performance

The Versalite sits in the lightweight-to-midweight warmth bracket, which suits it well for active hiking at moderate to fast pace. Its woven stretch face resists wind penetration far better than a knitted fleece construction, so you notice significantly less chill on col crossings and ridge sections where exposed positions amplify the wind effect. Breathability is adequate for steady paces but can feel warm on very steep, sustained climbs compared to a pure grid fleece construction.

Fit, comfort and layering

Helly Hansen cuts the Versalite with a trim, athletic profile that sits close to the body without restricting arm movement. The four-way stretch construction moves comfortably with you on technical ground, and the close fit layers cleanly under a waterproof shell without adding bulk across the shoulders or back.

Features that matter on the hill

• Attached hood provides immediate wind and light rain protection without reaching for a shell
• Full-zip design allows precise ventilation control on the move
• Cuffs and hem sit close against the body to seal out draughts on exposed ground

Price and value

At around £100-£110, the Versalite delivers strong value for a technical woven stretch midlayer. For hikers who regularly walk in exposed, windy UK conditions, the wind resistance advantage over a standard fleece justifies the price step up from a basic knitted option.

10. Montane Protium Hooded Fleece Jacket

The Montane Protium Hooded Fleece Jacket earns its place among the best hiking fleeces for its ability to pack down into its own chest pocket, giving you a genuinely compressible midlayer that takes up almost no space in a rucksack. Montane builds the Protium around a lightweight Polartec fleece construction that punches above its weight for warmth relative to what it packs down to.

Why it suits UK hiking

UK hikers frequently carry a fleece as a backup layer rather than wearing it constantly from the car park to the summit. The Protium suits that pattern well because you can stow it in seconds without needing a stuff sack. When a cold front moves in or the wind picks up on an exposed ridge, pulling the Protium from your rucksack takes no time at all, which matters when conditions deteriorate quickly on UK upland terrain.

Warmth, breathability and packability

The Protium sits in the lightweight-to-midweight warmth range, which makes it a practical choice for spring and autumn hiking as either a primary midlayer or a backup piece. Its Polartec fleece construction manages moisture adequately at steady hiking paces, though it lacks the stretch and active moisture management of Power Stretch Pro alternatives at a similar price point.

The Protium's packability sets it apart from most midlayers at this weight, making it an easy carry on routes where conditions can change fast.

Fit, comfort and layering

Montane cuts the Protium with a slim, technical fit that layers cleanly under a waterproof shell without bunching across the back or shoulders. The attached hood sits low enough to fit beneath a shell hood without creating uncomfortable collar height on multi-layer days.

Features that matter on the hill

• Packs into its own chest zip pocket for quick stowing
• Low-profile hood provides wind protection on exposed ground
• Hem and cuffs sit close against the body to seal out draughts

Price and value

At around £100-£110, the Protium delivers strong value for a packable technical fleece. For hikers who carry it as a versatile backup layer, the combination of packability and warmth makes it a practical choice at this price.

11. Mountain Equipment Lumiko Hooded Jacket

The Mountain Equipment Lumiko Hooded Jacket earns its spot among the best hiking fleeces by prioritising fast-drying performance in a midlayer that handles persistent UK dampness better than most alternatives at this weight. Mountain Equipment has decades of experience building technical clothing for demanding British conditions, and the Lumiko reflects that clearly.

Why it suits UK hiking

UK trails deliver rain, sweat, and river crossings in combinations that leave poorly chosen midlayers clinging to your skin for hours. The Lumiko uses a Polartec Power Dry fabric that transfers moisture away from your skin and dries faster than standard fleece constructions, which means it returns to a comfortable, warm state far quicker after a wet ascent or a short downpour without a shell.

For hikers who frequently cross boggy ground or walk in persistently wet upland conditions, fast-drying performance matters as much as raw warmth.

Warmth, breathability and fast-drying performance

The Lumiko sits in the lightweight-to-midweight bracket, making it well suited to active hiking across spring, summer, and autumn on UK trails. Power Dry fabric delivers a warmth-to-weight ratio that keeps you comfortable during steady paces without trapping excess heat during harder climbs where overheating becomes a real problem.

Fit, comfort and layering

Mountain Equipment cuts the Lumiko with a trim athletic profile that layers cleanly under a waterproof shell without adding unwanted bulk across your back or shoulders. The attached hood sits low against your collar and slides easily beneath a shell hood, giving you versatile layering options across a full day on the hill without constant adjustments.

Features that matter on the hill

• Polartec Power Dry fabric dries faster than standard knitted fleece alternatives
• Low-profile hood provides immediate wind coverage on exposed ridges
• Hem drops below the waistband to prevent cold gaps during steep ascents
• Chest zip pocket offers secure, accessible storage for a phone or snack

Price and value

At around £90-£100, the Lumiko represents strong value for a technical Power Dry fleece from a brand with genuine mountain credentials. For hikers who regularly walk in wet, unpredictable UK conditions, the fast-drying performance alone justifies the price step over a standard polyester midlayer.

12. Rab Ascendor Light Hoody

The Rab Ascendor Light Hoody rounds out this list of the best hiking fleeces as one of the most breathable technical midlayers Rab produces. Built around a stretch fleece construction that prioritises active moisture management over maximum warmth, it targets hikers who push hard and generate significant body heat on sustained climbs across UK trails.

Why it suits UK hiking

UK hillwalking generates sweat fast on steep ground, and the Ascendor Light handles that well. Its lightweight stretch fleece fabric moves moisture away from your skin efficiently during hard aerobic output, keeping you dry and comfortable even on sustained ascents in the Lake District or the Brecon Beacons. The full-zip design adds instant ventilation control so you can regulate your temperature precisely without stopping to strip layers.

Breathability and moisture management

The Ascendor Light sits at the lightweight end of the fleece spectrum, which makes breathability its primary strength. The fabric transfers moisture rapidly from your skin to the outer face where it can evaporate, so you stay significantly more comfortable during hard climbs than you would in a standard knitted fleece of equivalent weight. Wind resistance is limited by the open construction, so pair it with a shell on any exposed ridgeline.

Treat the Ascendor Light as a high-output active layer and it will outperform heavier fleeces at pace, but add a windshell the moment the wind picks up on exposed ground.

Fit, comfort and layering

Rab cuts the Ascendor Light with a slim, athletic profile that layers cleanly under a waterproof shell without bunching across your back or shoulders. The four-way stretch construction moves with you on technical ground and allows full arm movement without resistance, which suits scrambling routes in Snowdonia or the Scottish Highlands particularly well.

Features that matter on the hill

• Full-zip design provides precise on-the-move ventilation control
• Low-profile hood sits flat beneath a waterproof shell hood without adding collar bulk
• Hem drops to the hip to prevent cold gaps during steep ascents
• Stretch cuffs seal cleanly against gloves on cold morning starts

Price and value

At around £100-£110, the Ascendor Light delivers strong value for a technical stretch fleece from one of the UK's most respected outdoor brands. For hikers who cover high-output routes regularly and want a reliable midlayer that layers efficiently under a shell, it is a straightforward choice at this price point.

Final pick and next steps

Every fleece in this guide earns its place among the best hiking fleeces available for UK conditions in 2026, but the right choice depends on how you hike. If you push hard on steep ground and run warm, the Rab Ascendor Light or Patagonia R1 Air will serve you well. For reliable all-season performance as a true midlayer, the Rab Evolute or Montane Fury Lite hit the sweet spot between warmth and breathability. Budget-conscious walkers will find the Craghoppers CO2 Renu covers most UK conditions without the premium price tag.
