The best fleece jackets 2023: warm mid layers for your wild adventures

The best fleece jacket performs a variety of tasks. First and foremost, it keeps you warm when you head out into bitterly cold conditions. Unlike a puffer jacket, it doesn’t take up much room in your pack and, because of this, seasoned adventurers take multiple fleeces when they head out in winter. 

After all, many thin layers are better than one big jacket when it comes to layering and temperature regulation in the mountains. This is why lightweight fleeces are just as valuable as thicker fleeces for fall and winter use. We start our roundup with the finest lighter options, before moving on to chunkier tops.

Performance is vital. The best fleece jacket needs to be breathable, allowing moisture to escape during sweaty exertions, and it also needs to provide freedom of movement. In the event of a soaking, the very best fleece jacket is also quick drying, just like a quality base layer. Sometimes, your fleece will be one of your mid layers, happily sitting beneath a waterproof jacket.

The best fleeces are also perfect when acting as an outer layer in warmer, drier conditions, with some boasting water and wind resistant qualities. We love the Artilect Halfmoon Bio Pullover for its performance and eco-credentials, rating it as the best fleece jacket available today. We kick things off here.

A stylish and functional fleece top, the midweight Halfmoon Bio Pullover from Artilect makes for a fantastic outer layer during dry days and nights in the shoulder months, as the evenings and mornings get a bit chillier, and is an excellent midlayer, worn under a wind- and waterproof shell during cold and wet winter days spent hiking in the hills.  

Although most people will wear this fleece over the top of a baselayer, we found the Halfmoon pullover to be luxuriously comfortable next to the skin, and it’s highly breathable. The materials are 100% recycled, as all good fleeces should be, but Artilect also state that the PrimaLoft Bio fabric is biodegradable in landfill and ocean environments at the end of garment’s life – a circular process, where the specially developed fibres ‘return to materials found in nature’, which takes it to a higher level of eco-friendliness.

It’s worth noting that this top tends to size quite small, which can be useful when used a midlayers, but if you’re in doubt, go for a size bigger than you usually take.

Not warm enough for standalone use

The Montane Isotope Hoodie is a technical, ultralight hoodie designed for fast-and-light outdoor adventures. It tips the scales at a tiny 383g (men’s size medium) and has an athletic fit that we found makes it ideal for more fast-paced and dynamic activities like trail running, ski-touring, rock climbing or scrambling. The Isotope doesn’t have a DWR coating (see what is DWR for more details) and is unlikely to keep anything stronger than a moderate breeze out, but its STRIA Lite polyester fabric is highly breathable and uses a brushed backer that we found gave outstanding next-to-skin comfort, while offering more than enough warmth for summer evenings after sundown. 

Other features we liked included plentiful stretch in the fabric, a duo of zippered, mesh-lined pockets, a hood that’s streamlined and snug enough to fit under a helmet, and articulated arms that provide ample freedom of movement. On test, we found that it's simply one of the best lightweight fleeces out there.

We think the Arc’teryx Kyanite Hoody strikes the perfect balance between warmth, weight, mobility, and moisture management. It’s made with plush Polartec Power Stretch Pro fabric that combines rugged nylon face fabric with a plush, brushed interior to prove oodles of next-to-skin comfort with above-average ruggedness and durability. The Kyanite also has four-way stretch fabric, gusseted underarms, and uses articulated patterning to provide for a fuller and freer range of movement. This all makes it one of the best mid layers out there for climbing and scrambling, which we were doing plenty of during the test period. 

Other endearing features include a handy interior pocket that can accommodate most phones or compact cameras, an ergonomically shaped 'ScubaHood' that doesn’t flap in your eyes despite the lack of a cinch, and a 'No Slip Zip' that prevents inadvertent opening. While the fit on the Kyanite is fairly trim and figure-hugging, there’s more than enough stretch in the fabric to accommodate a fuller midriff. All in all, it promises reign for a long time as one of the best lightweight fleeces on the market.

Not the warmest fleece jacket

This handsome, highly functional fleece is happily at home everywhere from climbing crags to remote trailheads and urban bars. But don’t be deceived by its good looks – there are lots of non-compromising technical features on this top. The Nikwax material is relatively thin, but it’s wind and rain resistant, making the garment perfect for missions when you’re not sure what the weather has in store. 

We liked the fact that there are plenty of pockets on this top (two generous breast pockets, plus a third pocket – all zipped), so if you do wear it as an outerlayer, you have multiple storage options. The design and cut of the garment is excellent, giving it some real style and our movement was completely uninhibited on test. The hood is intended to go under a helmet, and the pockets are arranged so you can still access them while wearing a harness or backpack. The extra length covers your backside and means the top doesn’t ride up when you’re wearing a backpack, and the full-length zip means you can vent and get ride of excess heat.

As always, Páramo’s production methods are very environmentally conscious, with no PFC or polyfluorinated compounds used and the whole top can be recycled with Páramo after it has reached the end of its useful life. The Enduro is made in Bogotá, Colombia, by the Miquelina Foundation, which employs vulnerable women.

An ostensibly simple garment, this mega-light Mammot fleece proves invaluable in multiple outdoor scenarios. Easy to carry, we found its warmth-to-weight performance ratio is off the charts, especially when worn as a mid layer, when the thermal properties of the Bluesign-certified Polar Fleece fabric really come into their own. However, we discovered it’s also excellent as a lightweight long-sleeve outer layer, simply worn over the top of a T-shirt when the temperatures drop slightly. 

It has a high neck, with a full-length zip that tucks neatly into a little chin-protecting garage at the top to avoid snagging bristle, beard or skin. The cuffs and hem are elasticated, giving an improved fit and preventing drafts from getting in, and there are external thumb hook loops on the wrists, to avoid sleeves being pulled up when an outer layer is put on over the top – they are a bit fiddly to use, but avoid a gap being introduced to the fleece, which would compromise the warmth of the fleece.  

The top has reinforced shoulder panels, which increase its durability when regularly worn in conjunction with a backpack. It has two hand pockets on the outside, both of which zip shut, and there are a couple of large pouches on the inside, big enough to stash a sheet map or even a bottle of water (although, avoid putting small items in these pouches, as they have a small opening at the bottom, for some reason we’re yet to work out). The polar fleece fabric is made from entirely recycled material, so the enviro creds of this top are superb.

Some concerns over long-term durability

The Vigor is a lightweight microgrid stretch fleece that is designed to maximise breathability and regulate body temperature effectively – basically, to keep you warm when it’s a bit chilly but stop you overheating and getting too sweaty when you’re working hard. The fabric incorporates a thermo-regulating polymer that the brand refers to as ActiveTemp technology. This treatment has been applied to the inside of the fleece fabric, and when you get hot, it activates to soak up more of your sweat, then releases it through the fabric as you cool down. As such, it ticks all the boxes as a technical mid layer. It is close-fitting, with plenty of stretch for dynamic movement. 

On test, we found the gridded microfleece fabric to be soft and comfortable, as well as being lightweight and breathable. Other details have also clearly been considered carefully – there are integrated thumb loops in the cuffs, an elastic bound hood, a full-zip with a chin guard, a zipped chest pocket, and two zipped hand pockets, both of which are placed a little higher than usual so as not to be obstructed by a climbing harness or a backpack hipbelt.

Quick drying and easy to look after, it’s a midweight fleece that can be used all year round, from chilly summer evenings in camp to frosty winter mornings as part of a layering system. You might want to look at thicker option in seriously cold conditions but we found this top performed perfectly across three and half seasons. The high neck provides an extra little bit of protection, which is very welcome when things get cold and breezy. We tested the half zip version, which is more than adequate for this style of top, but there is a full-zip option too. The Daybreaker does lack thumb loops, which is our only real negative criticism (there’s no hood either, but many people prefer midlayers to be sans hood).

This straight-forward Polartec fleece top from Helly Hansen is a masterpiece in highly functional simplicity. Available for a sensible price in myriad colors for men and women, it does exactly what you want a fleece top to do without making a massive fuss about it. Made with 100% recycled poly material, as all good fleeces should be (these garments were the pioneering pieces of clothing for recycling, after all) it acts as an excellent insulating layer under a water- and windproof shell jacket when conditions are inclement, and works well as a nice-looking outer layer when the weather is better.

A sleek and fantastically warm fleece pullover that works just as well on your morning commute as it does deep in the backcountry. The Patagonia Better Sweater 1/4-Zip Fleece is an awesome bit of kit. Sleek and functional, it’s a stripped-back version of Patagonia’s ever-beloved Better Sweater Jacket, and it can be worn to practically any event. Featuring a straight fit that doesn’t ride up when you move, it’s comfortable, warm and understated. On test, we found it kept us warm on backcountry escapades and gave us a “cool” look in the office. 

Unlike the Better Sweater Jacket, the Patagonia Better Sweater ¼-Zip Fleece can’t be unzipped all the way. Instead, you wear it like a normal pullover, and it features a durable zipper that can be left open for some breathability or zipped up tightly to your chin for maximum warmth. 

Unlike on other zips that come up so high, however, the large YKK zip on the Better Sweater doesn’t rub on your chin or irritate you in any way, and the soft-brushed fleece liner around the inside of the neck feels soft and gentle when zipped tight.

Reasons to avoid

Cuffs and hem not elasticated

The Yakutian is a versatile fleece that can be worn as a mid layer or as an outer layer, thanks to a dense-knit hardface fabric that is designed to be much more wind resistant than standard fleece. It also adds durability, making this jacket less susceptible to pilling, as well as abrasion. But that tough exterior doesn’t mean sacrificing comfort, since the fabric is double-sided, retaining a brushed inner that offers warmth and good wicking abilities. You also get a deep half zip for venting, a zipped chest pocket and thumb loops at the cuffs.

On test, we found that it’s a warm, soft and comfortable jacket, thanks to elastane in the fabric that gives it plenty of stretch and flatlock seams that don’t rub. It also has good articulation, with generous length and coverage. It may sometimes prove a bit too warm since the dense fabric seems to limit breathability a little. But this is a great fleece jacket for cold and breezy conditions.

The Helly Hansen Power Air Heat Grid jacket is a mid layer fleece designed to greatly reduce the problem of microfibre shedding. To achieve this, its polyester fibres are encapsulated within pockets that trap air to generate warmth, a bit like the baffles of a down jacket. Since the loose polyester fibres are trapped in a tightly woven outer, there is up to 80% less microplastic release when wearing or washing the jacket. You’ll appreciate this if you don’t like fleeces that leave fuzz all over your other clothes too. 

The face fabric has been similarly developed with durability in mind, resisting pilling or bobbling. The jacket itself has an ideal semi-tailored fit – which we found was not too tight and not too baggy on test – with zipped hand pockets and thumb loops at the cuffs. A little stretch in the fabric ensures pleasant everyday comfort, and there’s plenty of length in the arms and torso for ample coverage. Lastly, the fabric is made from recycled polyester, strengthening its eco credentials. If you are mindful of the impact of synthetics, but appreciate their performance, this is a top choice. It is a fraction heavier than most other fleece jackets of similar warmth, but that seems a small price to pay for a greener garment.

Rather than being fully synthetic, the Balder is made from an unusual blend of recycled wool, polyester and nylon. This ensures softness yet also durability, as well as improved sustainability. The wool is sourced from an Italian supplier, which spins new yarn from offcuts and old garments. It’s a typically considered and conscientious approach from the Swedish brand, which is known for its strong environmental stance as well as its high-performance technical gear. This jacket is designed for cold weather use, so delivers high levels of warmth. On test, we discovered that it's cosy, luxurious and not at all itchy. 

It also breathes better than you might expect for such a heavyweight layer. The overall cut is well tailored, with a trim fit, long arms and a scooped rear hem for good all-round coverage. The shaped cuffs cover the wrists and the backs of the hands well. The collar is snug and locks in heat very effectively, without feeling constrictive. The main zip and the hand pockets have chunky pull tabs that are easy to grip while wearing gloves. Overall, it’s a mid layer that offers good technical performance and which is stylish enough to wear as part of your everyday winter wardrobe too.

The Rolpa is a stylish crossover layer that you can take on the hills but also wear as part of an everyday wardrobe. As a lightweight fleece, it doesn’t deliver huge amounts of warmth, but is the ideal jacket to throw on over a base layer for hillwalking or over a T-shirt for daily wear. On test, we found it to be extremely soft and it's also comfortable all day long. The full zip has a soft chin guard with a classy leather and brass pull-tab zipper. The zipped hand pockets also have cord pulls and a taped ‘prayer flag’ trim, which is also found inside the base of the collar. 

The fit of the Rolpa jacket is spot on, with a slim silhouette but enough length in the arms and torso for full coverage. The panel construction also thoughtfully places seams away from the tops of the shoulders for added comfort under a shell, or if wearing a pack. Best of all, however, is the fact that the Rolpa is actually made in Nepal, with the brand providing education and resources for children in Nepal for every product sold.

The Fusion Fleece is a chunky, heavyweight insulator that is designed to be worn as outerwear or as a conventional mid layer – it worked well as both during our testing period. As such, it employs a hybrid construction, using a heavy-gauge fleece with a knit face as the main fabric, interspersed with lighter stretch fleece panels. This gives it a stylish and contemporary look while boosting performance in terms of overall warmth for weight, breathability, moisture management, comfort and fit. It’s also been made with durability in mind, with an anti-pilling fabric treatment and double-layer stretch cuffs, so it ought to offer good long-term value – and has a reasonable price point to match. It doesn’t skimp on features either, with a full-length reverse-coil main zip, which has a soft chin guard and is backed with a baffle. You get a zipped chest pocket and two open hand pockets. The cuffs also incorporate thumb loops – always a handy feature, as far as we’re concerned – while the hem has a drawcord adjustment.

The price range for fleeces is extraordinarily wide, with some having eye-wateringly high price tags, but this functional fleece from Decathlon’s Quechua’s range is available for an excellent price. And, while it is a rather no-frill garment, from the prosaic product name to the colors it comes in, this is a great little lightweight layer to keep in a backpack in late summer, when you might need it over a T-shirt to keep the evening chill off, or as a midlayer under a windproof shell as the warmer months give way to a breezier autumn days and longer nights. There’s no hood, but it does have a high collar, which we found kept our neck warm on test. 

The fleece has a full-length zip, but do bear in mind there is no zip garage at the top, so you can catch your beard or skin in the teeth. There are two hand pockets, both of which zip shut to secure valuable items such as phones, and inside there are two cavernous mesh pouches, which will take a map and more. There is a lack of bells and whistles here, unsurprisingly given the price, but one easy addition we would like to see is a thumb loop, to avoid the sleeves riding up when you pull on a top layer. However, we will happy excuse this because, brilliantly, the entire top is made from recycled polyester.

This midweight fleece from British brand Mountain Warehouse works as an outerlayer when conditions are dry, or as a midlayer below a waterproof coat when the clouds start to leak. If you do happen to get caught out in a shower, the fleece fabric will continue to provide thermal protection even when damp, and we found that it dries quickly. 

The material, which is entirely recycled, is both comfortable and warm. The (poorly named in our opinion) Relic has a pair of zipped pockets on the outside, for keeping essentials such as car keys safe, and a couple of open-top fabric pouches on the inside. It has a comfortable collar, which is high enough to keep breezes at bay, and a full-length zip. There is no chin protector, however, and it also lacks thumb loops, but the arms have smooth panels on the outside, which means they don’t bunch up so much as others when you pull on an outer layer.

How we test fleece jackets

Our reviewers test fleece jackets in a range of environments and conditions, both as a midlayer and an outer layer. Features (including thermal properties, style, breathability, materials, comfort, pockets, hoods, zips) are tested against claims made by the brand, and we assess factors such as value for money, durability, functionality and environmental impact.

How to choose a fleece jacket

As with almost all outdoor kit, the best fleece jacket for you will depend on a number of factors – not least, when and where will you wear it. In addition, though the primary function of a fleece jacket is to provide insulation, this can be balanced with other factors such as weight, bulk, breathability and pack size.

As a rule of thumb, the thicker and heavier the fleece fabric, the warmer it will be. On the flipside, that will also generally make it less breathable. The best lightweight fleeces are ideal for summer adventures, when you're going to be moving faster and it's going to be warmer anyway. It will probably stay in your day pack until you hit cols, ridges and summits, but that's fine.

If you’ll be moving fast or tend to run hot, bear in mind that most heavyweight fleeces will be too warm for active use – though they’re great for standing around in the cold or if you're belaying during a climb. Numerous different types of fleece fabrics have also emerged, generally developed with one of two things in mind: to either increase the warmth for weight of the garment or to enhance its breathability, so it can be worn during high-output, energy-intensive activities.

Fabric type

Originally, ‘fleece’ referred specifically to polar fleece, a synthetic fabric made from polyester. Today, however, a ‘fleece’ has become a catch-all term for pretty much any warm and cosy mid layer jacket that does the job of a traditional wool sweater, jumper or pullover. As such, you might find some ‘fleece jackets’ that aren’t actually made from polyester fleece at all, or which are a hybrid of synthetic and natural fibres (including wool).

Popular forms of Polyester fleece available now include classic polar fleece (in various weights), microfleece (tightly woven pile), gridded microfleece (with good breathability for active use), shearling/pile fleece (heavier weight), high-loft fleece (super-fluffy, offering the best warmth for weight), hardface/techface fleece (designed to prevent to pilling), Thermal Pro (developed by Polartec, typically with a knitted face) and Power Air (also from Polartec, designed to counter the issue of microfibre shedding).

Design

While the fleece fabric type and weight primarily dictate the warmth and breathability of a fleece jacket, factors like construction and overall design also have an impact. Many of the best fleece jackets now utilise a zoned or hybrid construction. This means that panels of different weight fabrics are employed to make the garment more breathable or stretchy, resulting in greater comfort and better articulation for active use. You might find lightweight or stretch inserts used along the sides or under the arms of a jacket accordingly.

Features

Since they are primarily designed as mid layers, technical fleece jackets don’t always feature a hood, and some may not even have pockets. Obviously, these are less important if you’re wearing your fleece underneath a shell, since your outer layer is likely to have its own hood and pockets. Most fleeces that lack a hood still have a stand-up collar to help lock in core warmth though.

Of course, many users do prefer a fleece with a hood and pockets. A hood adds valuable insulation and can’t get lost or blow off your head, unlike a hiking hat. It is also easier to wear beneath a helmet. Hand or hip pockets are useful to keep hands warm as well as for storage for items like hiking gloves. So are zipped chest pockets or even arm pockets. These all add versatility, especially if wearing a fleece as a standalone layer.

Fleece jackets will have a full-length main zip. Fleece pullovers just have a quarter zip or a deeper half zip at the neck. Look for zips that are backed with a baffle, which helps to prevent draughts and also adds to overall comfort. Similarly, a chin guard at the top of the zip is always a welcome detail, preventing irritation.

Cuffs and hems should be close-fitting for optimum thermal efficiency. Some fleeces have elasticated cuffs and hems (or even a hem drawcord) to help lock in heat.

One feature that is commonly neglected are thumb loops. These can be used to help cuffs cover the wrists and stop the sleeves of your fleece from riding up, which is good in cold conditions. If you’re wearing liner gloves, thumb loops can also eliminate any exposed skin, which is great for winter mountaineering and snow sports.

Weight and pack size

A fleece is generally worn on the hill rather than carried, but on warm days you may want to roll it up and stuff it in your backpack, so weight and pack size can be important considerations. On an expedition, you might want to stash your fleece in a dry bag with other spare clothes. They are blessedly warm on cold nights and can double up as a pillow. 

A heavy and bulky fleece that takes up almost all the space in your pack and weighs you down is not particularly practical. That’s why warmth for weight and compressibility (or packability) are still important factors when looking for the best fleece jackets, even though fleece doesn’t offer the same performance in this regard as, say, a down ‘puffer’ jacket. The best lightweight fleeces combine performance with packability.

Fit

The thermal efficiency and comfort of a fleece is greatly influenced by how it fits. Loose fitting cuffs, hems and hoods can all leak heat, limiting warmth. Generally, the best fleece jackets should allow room for a base layer underneath but should be trim enough to fit underneath your windproof or waterproof shell. Technical fleeces are usually stretchy and close-fitting. If you plan to wear a fleece as casual clothing, you might want something a little more accommodating.
