Our team of experts at The Great Outdoors has tested over a 100 fleece jackets over the years, from the dawn of synthetic fleece as used in outdoor clothing. This includes some of the best fleece jackets for men and women which are put through their paces in mountain environments.
From unlikely origins in toilet seats, midlayers for hiking have come on leaps and bounds over the decades. Now, there’s a wide variety of designs to choose from, from fleeces to softshell-style ‘active insulation’. The aim is to strike a balance between warmth, breathability and wicking, depending on your activity and expected weather conditions.
Below you will find a whole range of fleeces, to suit whatever style you’re looking for.
Montane Fury Lite Hooded Jacket
Alex Roddie’s Best in Test
I’ve found this the ideal fleece for general three-season use. Although I’ll still reach for the Allez Micro in milder conditions, this one is a bit warmer, a bit cosier, and with more casual styling.- Comfortable and soft
- Good warmth for three-season use
- Hight stretch
- Breathability
- Nothing
| Quick specs | |
|---|---|
| Price: £100 Weight: 341g Materials: 51% recycled polyester, 39% nylon, 10% elastane Hood: helmet-compatible, elasticated, no adjustment Front closure: one-way zip with internal flap Pockets: 2x zipped external handwarmer Hem: no adjustment Cuffs: simple Womens/mens version: both Sizes: men: S–XXL; women: 8–16 montane.com |
The Montane Fury Lite is a lightweight, versatile fleece jacket that offers warmth and versatility. It is designed as a standard zipped fleece jacket with a basic hood and two handwarmer pockets, making it a popular choice for its athletic fit. The jacket’s high stretch allowed me to have exceptional freedom of movement, and the outer face moves freely under the shell, while the inner face is soft and fluffy. Although it is less capable in varying conditions than the more technical Allez Micro, the Fury Lite is good at resisting overheating, providing excellent moisture wicking and breathability.
It is also more wind-resistant than the Allez Micro. Montane claims that the abrasion-resistant fabric has been engineered for increased durability, but no evidence of wear has been observed. The hood on the Montane Fury Lite is perfect, providing good coverage for the face without any adjustment. The jacket is ideal for general three-season use, but is a bit warmer, cosier, and with more casual styling. The value is also decent.

Outdoor Research Women’s Deviator Hoodie
Lara Dunn’s Best in Test
This is a highly technical and warm midlayer that also works well as a stand alone jacket and doesn’t come with a weight penalty.- Stretchy
- Lightweight
- Very breathable
- Could use a drawcord of some sort
| Quick specs | |
|---|---|
| Price: £200 Weight: 341g (women’s large) Materials: stretch shell 90% nylon/10% elastane, wind resistant shell 95% polyester/5% elastane, lining 100% polyester – VerticalX Octa, ActiveTemp fabrics Hood: same fabrics as body with soft peak Cuffs: soft stretch, same fabrics as body Hem: same stretch fabrics as body Pockets: 2 x handwarmer, 1 x chest Sizes: XS-XXL Women’s/Men’s version: both www.outdoorresearch.com |
Outdoor Research’s Deviator is a lightweight hooded jacket that combines lightweight softshell and insulation fabrics with stretch for reliable warmth and wind resistance. The jacket’s sleek, stretchy fit is not overt, providing excellent mobility and making it ideal for high-energy activities. The jacket’s fabrics are zoned, with a stretch knit fluffy fleece lining backing wind-resistant ultralight softshell panels at the front, hood, shoulders, and tops of sleeves. The rest of the jacket features highly breathable and moisture-wicking stretch waffle knit panels.
The Deviator is light and stretchy, providing a surprising level of warmth for its weight. It is best suited for cool or warmer temperatures on its own, but can layer up under a waterproof shell due to its low bulk fit. It is a lightweight and compact option for rucksacks, and its wind-resistant panels offer protection from rucksack straps. The jacket is a highly technical and warm midlayer that can also be used as a stand-alone jacket without a weight penalty.

Salewa Agner Polarlite Hooded Jacket
Fiona’s Russell’s Best in Test
Although the Salewa Agner Polarlite Hooded Jacket was the priciest of the jackets Fiona Russell tested, it’s the one she would choose to buy.- Fabric
- Fit
- Features
- Quality
- Price
- Sizing
| Quick specs | |
|---|---|
| Price: not available in US | £140 (available from Salewa) Weight: 370g (UK12) Materials: Duratretch PFC-free bluesign 151g/sqm – 85% Polyamide, 15% Elastane – and Polarlite Pontetorto bluesign 225g/sqm – 94% Polyester (recycled), 6% Elastane Hood: Yes Front Closure: full zip Pockets: 2 Hem: Plain Cuffs: Elasticated Men’s version: Yes Sizes: UK4 to 14 |
The Salewa Agner Polarlite Hooded Jacket is a high-quality, versatile mid-layer jacket that features a hybrid construction with Polarlite for a fleecy and insulating inner, and Durastretch inserts for abrasion resistance. The jacket is body-mapped, with different fabrics matching body needs, and is made with recycled polyester and bluesign-approved fabrics.
The jacket is windproof and I found it suitable for both casual office wear and outdoor activities. It also has a Durastretch hood with side openings for helmet straps and two high-set zipped pockets. The full front zip is made of chunky plastic. The jacket is designed for an “athletic fit” and offers great freedom of movement. Although I found the sizing to be bit difficult to fit, the Agner is a top choice for those seeking a high-quality, versatile jacket.

Alpkit Woodsmoke
Peter Macfarlane’s Best in Test
Peter Macfarlane says the Alpkit Woodsmoke is a genuinely do-it-all top with sustainable manufacturing origins and awards it his ‘Best in Test’.- Fit
- Comfort
- Fabric
- No lower pockets
- Poppers won’t suit everyone
| Quick specs | |
|---|---|
| Price: $99.99 | £89.99 (available to buy from Alpkit) Weight: 386g size L Materials: 95% Thermocore polyester/ 5% spandex fabric, metal poppers Hood: No Front Closure: metal poppers Pockets: two high chest, flapped and poppered Hem: plain Cuffs: shirt style, popper adjustable Sizes: XS to XXL Women version: Yes |
The Alpkit Woodsmoke comes in a light and stretchy polyester fabric with a brushed surface which feels very pleasant against the skin. The Thermocore fabric is described as having hollow core fibres which trap air for insulation and there is good warmth here despite the noticeably thin fabric. during testing I wore the Woodsmoke over short and long-sleeved base layers and often it’s been layered under a shell or windshirt. The insulation level for layering is useable outside of winter temperatures. I’ve found the moisture management very good too. While I can wet out the back area under a pack, it does dry quickly.

Smartwool Women’s Intraknit Active Full Zip Jacket
Lara Dunn Highly Recommends
It’s a genuinely versatile jacket and good for a wide variety of temperatures plus it gets a big tick for Smartwool’s ethical and environmental stance.- Very stretchy
- Wind resistant panels
- Good temp stability
- Neat fitting
| Quick specs | |
|---|---|
| Price: £149.99 Weight: 387g (women’s large) Materials: 53% merino wool/21.3% lyocell/21% polyester/5% elastane Features: wide soft collar, wind resistant panels, zoned breathability Sizes: XS-XL Women’s/Men’s Version: Women’s (men’s direct equivalent available) www.smartwool.co.uk |
The Intraknit Active jacket is a versatile layer made from Smartwool’s merino wool, blended with other performance yarns and fabrics. It offers warmth, temperature maintenance, odour tackling, wind resistance, and high levels of stretch. The jacket’s slim fit makes the fabric stretchy and breathable, but it’s important to consider its use as a midlayer under a shell.
In use, it’s a comfortable layer in various weather conditions, delivering stable body temperature in temperatures from mid-single figures to mid-teens. The jacket’s high breathability and moisture transport properties compensate for the wind resistance offered by the front panels. A wind-resistant fabric across the shoulders could be improved for protection from rucksack strap wear.
When worn with a shell layer, the jacket’s sleek fit and cozy collar make it an impressive insulating layer. Although heavier than some midlayers, it’s not heavyweight and can be used as a daypack extra layer on changeable days. The jacket is versatile and good for a wide variety of temperatures, and it aligns with Smartwool’s ethical and environmental stance, pushing for more sustainable outdoor clothing.

Black Diamond First Light Stretch Hoody
Alex Roddie Recommends
Overall, I think this is a great choice for Scottish winter backpacking or mountaineering.- Warmth for weight
- Breathability
- Freedom of movement
- Hood could be bettter
- Expensive
| Quick specs | |
|---|---|
| Price: £260 Weight: 391g Materials: 20D nylon stretch ripstop with PFC-free DWR, Primaloft Gold Active insulation (100% polyester), nylon stretch woven lining Hood: helmet-compatible, single rear adjustment Front closure: one-way zip with internal flap Pockets: 2x zipped external handwarmer, 1x zipped external chest Hem: adjustable drawcord Cuffs: elastic Womens/mens version: both Sizes: XS–XL blackdiamondequipment.com |
The Black Diamond First Light Stretch Hoody is a perfect synthetic midlayer for winter, offering freedom of movement, warmth without being too warm, and a hood that reduces the need for hats and balaclavas. The jacket has a perfect fit, with room for a light fleece underneath and good coverage for the backside. The outer face fabric is soft and durable, and the inner fabric is soft and cosy, with just the right amount of Primaloft Gold insulation for effective winter use. The materials used are Bluesign-approved and PFC-free.
The First Light Stretch Hoody serves as a great choice for spring or summer backpacking, but its high breathability may not provide as good wind resistance as most dedicated insulated jackets. The hood is helmet-compatible but doesn’t offer enough coverage for the face and mouth, which can result in cold breezes. Despite this, it moves well with the head. Overall, the First Light Stretch Hoody is a great choice for Scottish winter backpacking or mountaineering.

Inov-8 Venturelite mid hoodie review
Fiona Russell Recommends
I like that inov-8 have paid attention to looks as well as outdoor practicalities, plus there is an extra attention to detail with a small reflective feature at the rear.- Fit
- Weight
- Warmth
- Fiddly zip
| Quick specs | |
|---|---|
| Price: $140 | £110 (available from inov-8 & Sports Shoes) Weight: 267g (UK10) Materials: 92% recycled polyester / 8% elastane Hood: Yes Front Closure: Full zip Pockets: 2 Hem: Elasticated Cuffs: Elasticated with thumb loops Men’s version: Yes Sizes: UK6 to 16 |
The female-specific and athletic fit of the inov-8 Venturelite mid hoodie is well designed and flattering. The neat and tight hood, longer torso and arms with thumb-loops combine to offer extra insulation around the head, hips and wrists. Unfortunately, for me the sleeves are not long enough to make use of the thumb-loops without cutting off circulation. The textured hexagon inner knit fleece is lovely and soft against the skin, while the outer is a smooth polyester that keeps its look after many wears and washes.

Arc’teryx Delta ½ Zip hoody
Fiona Russell Recommends
Fiona Russell finds the Arc’teryx Delta ½ Zip hoody a cleverly designed mid-layer with good moisture management and weight-to-warmth ratios.- Lightweight
- Fit
- Technical design
- Thin fabric
- Wind permiable
| Quick specs | |
|---|---|
| Price: $180 | £130 – available to buy from Arc’Teryx Weight: 221g (small) Materials: Polartec® Power Dry® fleece Hood: yes Front closure: half zip Pockets: 1 Hem: Plain Cuffs: Elasticated with thump loops Men’s version: No (full zip jacket version for men) Sizes: XS to XL |
The design of the Arc’teryx Delta ½ Zip hoody is trim, athletic and figure hugging. The sizing is accurate with the addition of a longer torso and longer arms, plus thumb-loops. The “ScubaHood” fits under a helmet, should you need to wear one, and has a panel that can be tucked behind the head or worn as a neck gaiter or balaclava. This is a clever detail and useful in colder conditions. Note that if you wear glasses, the neck gaiter causes them to steam up if you have it over your nose.

Berghaus MTN Seeker ST Jacket
Peter Macfarlane recommends
Peter Macfarlane says the Berghaus MTN Seeker ST Jacket offers good warmth for weight and an incredibly comfortable fit.- Comfort

- Nothing

|---|---|
| Price: International shipping available | £130.00 (available to buy from Berghaus) Weight: 384g (size L) Materials: Polartec Power Stretch Pro Hood: No | Front Closure: full zip Pockets: two zipped mid height Hem: stretch binding Cuffs: stretch binding with elastic thumb loops Sizes: XS to 2XL Women’s version: Yes |
The Berghaus MTN Seeker ST Jacket is part of Berghaus’ Extrem range which is their top end mountain specific collection so I was looking for simple, practical and durable during testing. The fit is close with long arms and long body which is excellent under other layers. The articulation is perfect with no hem movement at all with both of my arms raised over my head.

Haglöfs ROC Flash Mid Hood Men
Peter Macfarlane Recommends
Peter Macfarlane recommends the Haglöfs ROC Flash Mid Hood, saying it is both comfortable and sustainably made.- Fit
- Fabric
- Comfort and hood
- Pocket design
| Quick specs | |
|---|---|
| Price: not available in the US | £110.00 (available to buy from Haglofs) Weight: 372g size L Materials: recycled polyester grid backed fleece Hood: Yes Front Closure: full zip Pockets: two zipped mid height Hem: plain Cuffs: plain Sizes: S to XXL Women’s version: yes |
The Haglöfs ROC Flash Mid Hood is the only top reviewed this time that has a hood, which proved to be excellent. It has a sculpted, close-fitting shape that moved with my head without restricting the movement or obstructing my view. The warmth was enough to replace a beanie or Buff, plus there’s the added convenience of it always being there. The light fabric means that the hood doesn’t bunch up annoyingly when rolled down under a shell. It also acts well as a collar when the zip is pulled up to the top, where there is welcome chin protection detailing.

Keela Scree Packaway Smock
Alex Roddie’s verdict
Overall, this is too warm as a midlayer for most British hiking. But if you’re going somewhere seriously cold, and need a durable option with lots of pockets, this is worth a look. Value is also good.- Durability
- Roomy cut
- Pockets
- Warmth
- Value
- Heavy and Bulky
- Freedom of movement
| Quick specs | |
|---|---|
| Price: £139.95 Weight: 486g Materials: 100% nylon ripstop Flylite Ultra shell, 60gsm Primaloft Gold insulation (100% polyester), 100% polyester lining Hood: none Front closure: quarter-length zip with internal flap Pockets: 2x zipped external handwarmer, large front kangaroo pocket Hem: adjustable drawcord Cuffs: elastic Womens/mens version: unisex Sizes: XS–XXL keelaoutdoors.com |
The Keela Scree Packaway Smock is an interesting option that can be used either as a midlayer fleece in very cold conditions or as a standalone insulated jacket. The smock has a quarter-length zip from collar to solar plexus, and beneath this you’ll find the enormous kangaroo pocket – big enough to stash plenty of hill snacks plus your hat and gloves. The whole smock can pack away into this pocket. There’s a fantastic storm flap over the zip. Thanks to the highly water-resistant fabric, I’ve found that most things stay dry in this pocket in anything short of a downpour. The other provided pockets are two handwarmer ones that meet in the middle, meaning that there’s a lot of storage space here too.
Overall, the Keela Scree Packaway Smock is too warm as a midlayer for most British hiking. But if you’re going somewhere seriously cold, and need a durable option with lots of pockets, this is worth a look. The value is also good.

How we test
Lara Dunn
Lara usually takes a size UK14 or sometimes a UK16 in high street clothing, depending on fit/shape/purpose of garment. These midlayers were mostly tested on short and longer day walks in the Malvern Hills during a chilly (down to low single digits), wet late winter and through spring (up to around 14 degrees), with additional day trips to the Brecon Beacons and Black Mountains.
Fiona Russell
Fiona tested the fleece and light mid-layers on the trails, hills and mountains of Scotland and in a range of weather conditions. She is a keen runner and Munro and Corbett bagger. She usually wears a size small or UK10, although she is fairly tall at 5ft 8in and has long arms. The products were weighed on home digital scales.
Alex Roddie
Alex tested his midlayers on a series of day hikes and overnight backpacking trips in the Cairngorms, West Highlands, and lowlands of Angus and Perthshire. All weights are as measured on Alex’s digital scale (men’s size Medium).
Peter Macfarlane
Peter began testing these samples on the Munros last winter and they’ve been in constant use through to the summer of this year on hill days, low level tracks and trails, general outdoor exploring and also as regular everyday wear. Peter’s role as a Woodland Trust ranger is important to him for judging the performance and the durability of gear with regular traverses of the Kilpatrick Hills in all weathers and at any time of day or night.
Features of a good fleece
Pockets
Napoleon or bicep pockets are good for smaller items. Torso pockets are larger but all can interfere with harnesses and rucksack straps so check fit. Zips keep things safe inside.
Hood
Provides extra warmth on cold days, but can be a faff under other layers.
Front Zip
Full length or not… You decide! Some are sold as “interactive” zips that combine with a waterproof to make a padded 2-in-1 jacket. The downside to this system is a cold spot down the front where the zips meet.
Fit
Close fitting stretchy fleeces are good for layering underneath other garments. Length helps keep vital organs warm and prevents riding up.
Cuffs
Some have a hook and loop tab or thumb loops to deal with drafts.
Hem
Stretchy edge finishing or a drawcord help to keep drafts out and prevent riding up, but check the drawcord/toggle wont chafe under your rucksack.
