Author: Trekitt Gear Team
With years of experience hiking, hillwalking and exploring the UK’s mountains and trails, our team knows what makes a great fleece jacket. We’ve tested fleeces in everything from cool summer mornings to freezing winter hikes, giving us first-hand experience of how different weights, fabrics and designs perform. In this guide, we share our top fleece recommendations, explain how to choose the right one and help you find the best layer for your outdoor adventures.
Most hikers own more than one fleece, and once you’ve found one you really like, it’s easy to see why. They’re warm without being bulky, breathable enough for active days and comfortable enough that you’ll probably keep wearing yours long after you’ve got home.

How to Choose the Best Fleece Jacket
Choosing the right fleece isn’t just about picking the warmest option. The best fleece for you depends on how and where you spend your time outdoors. A lightweight layer that feels perfect on a summer hike may leave you cold on a winter summit, while a thick fleece can quickly become too warm during fast-paced walks. Understanding the key differences will help you choose a fleece you’ll reach for time and time again.
Why Do Hikers Wear Fleece Instead of Cotton?
While cotton feels comfortable around town, it isn’t the best choice for active days outdoors. Once it becomes wet from rain or sweat, it absorbs moisture and takes a long time to dry, leaving you feeling cold and uncomfortable.
Fleece works differently. The synthetic fibres trap warm air while allowing excess heat and moisture to escape, helping you stay comfortable during long walks and changing conditions. It also dries much faster than cotton, making it a far more reliable layer for hiking and hillwalking.
Warmth vs Breathability
Finding the right balance between warmth and breathability is one of the most important parts of choosing a fleece.
If you mainly enjoy fast-paced hiking or steep climbs, a lighter, more breathable fleece will help regulate your temperature and prevent overheating.
For slower walks, colder days or regular rest stops, a warmer fleece provides better insulation and helps retain body heat when you’re less active.
Lightweight vs Midweight vs Heavyweight Fleece
Fleeces generally fall into three categories.
Lightweight fleeces
They are ideal for spring and summer hikes, trail walking and active pursuits where breathability matters most. They also make excellent mid layers beneath waterproof jackets.
Midweight fleeces
They offer the best all-round versatility. They provide more warmth without feeling bulky, making them suitable for three-season hiking, everyday outdoor use and general hillwalking.
Heavyweight fleeces
are designed for cold weather, winter hiking and lower activity levels. They prioritise insulation over ventilation and are ideal when temperatures really begin to drop.
Hood or No Hood?
A hood adds valuable warmth around your head and neck, making it a great choice for cooler conditions or exposed ridges where the wind can quickly steal body heat.
A hoodless fleece offers a cleaner fit beneath waterproof jackets and is often preferred by those who already wear insulated or waterproof hoods. It also feels less bulky for everyday use.
Full Zip or Half Zip?
Full zip fleeces are the most versatile option. They’re easy to put on and take off, provide excellent ventilation and work well throughout changing conditions.
Half zip fleeces are often slightly lighter and simpler in design. They retain warmth well and are a popular choice for walkers looking for a minimalist layer.
Stretch and Freedom of Movement
Many modern fleeces include stretch fabrics that move naturally with your body. This makes a noticeable difference when scrambling, reaching for trekking poles or carrying a rucksack over long distances.
A fleece with good stretch feels less restrictive and remains comfortable throughout a full day on the trail.
Layering with Waterproof and Insulated Jackets
One of the biggest strengths of a fleece is how easily it fits into a layering system.
On cool, dry days, a fleece often works perfectly as your outer layer. When the weather turns, simply add a waterproof shell to protect against wind and rain without sacrificing breathability. In winter, combining a fleece with an insulated jacket creates a warm and adaptable system for mountain days and freezing temperatures.
Choosing a fleece that layers comfortably with the rest of your outdoor clothing will make it one of the hardest-working pieces of kit in your wardrobe.
Best Fleece Jacket for Hiking
Rab Nexus Hoody
If you asked our team to recommend one fleece for hiking, the Rab Nexus Hoody would come up again and again. It’s one of those jackets that just works. Light enough to throw in your pack, warm enough for cool mornings and summit stops, and breathable enough that you rarely feel the need to take it off once you’re on the move.
That’s what makes it such a brilliant hiking fleece. As you start climbing and your body warms up, it lets excess heat escape instead of leaving you feeling hot and clammy. Then, as soon as you stop for a brew or lunch, it traps enough warmth to keep the chill away.
It’s also one of those fleeces that earns a permanent place in your rucksack. It packs down small, weighs very little and is always useful when the temperature drops more than expected. If you’ve ever looked at the forecast before a hike and thought, “I’ll chuck a fleece in just in case,” this is exactly the sort of fleece we’d choose.
The close-fitting hood is another feature we really like. It adds a surprising amount of warmth when the wind picks up without adding unnecessary bulk, and it sits comfortably under a waterproof shell when the weather inevitably changes.
For most people, this is a true three-season fleece. It’s ideal from spring right through to autumn, and once winter arrives, it continues to shine as part of a layering system under an insulated or waterproof jacket.
Why we love it
- Comfortable enough to wear from the start of your hike until the finish.
- Breathes brilliantly when you’re working hard uphill.
- Packs away so easily you’ll hardly notice it’s in your rucksack.
- A versatile layer you’ll use on everything from local walks to mountain days.

Best Fleece for Everyday Outdoor Use
Fjällräven Abisko Trail Fleece
Not every fleece needs to be built purely for the mountains. The Fjällräven Abisko Trail Fleece is the one we’d recommend if you want a jacket that feels just as at home on a woodland walk as it does on your daily commute or a weekend away.
It has that classic Fjällräven feel: comfortable from the moment you put it on and smart enough that you won’t rush to take it off when you get indoors. At the same time, it’s more than capable of handling long walks, campsite evenings and travel days thanks to its durable construction and practical design.
It’s the sort of fleece you’ll probably end up wearing more than you expected. One day it’s keeping you warm on a countryside walk, the next it’s packed for a weekend trip or thrown on for a cool evening in the garden. If you’re only planning to own one fleece, this kind of versatility is hard to beat.
Why we love it
- One fleece that genuinely suits both outdoor adventures and everyday life.
- Comfortable enough to wear all day without feeling bulky.
- Durable construction that stands up to regular use.
- A timeless design you’ll still be happy wearing years down the line.

Best Lightweight Layering Fleece
Montane Protium Lite Hooded Fleece
Some fleeces are designed to be worn on their own, while others are made to slot perfectly into a layering system. The Montane Protium Lite Hooded Fleece definitely falls into the second category. If you spend your time hiking in changeable conditions, this is the layer we’d keep close at hand.
It’s incredibly lightweight and packs down small, so it hardly takes up any room in your rucksack. Despite its low bulk, it provides just enough warmth to take the edge off a cool morning without feeling too warm once you’re moving.
Where it really stands out is breathability. During steep climbs or fast-paced hikes, it lets heat and moisture escape, helping you stay comfortable instead of ending up damp from sweat. It also dries quickly, so if you work hard on the trail or get caught in a light shower, it won’t stay wet for long.
Its slim fit makes it an excellent partner for a waterproof shell. It layers smoothly underneath without bunching up, creating a comfortable system that can cope with everything from cool summer mornings to unpredictable mountain weather.
Why we love it
- One of the lightest fleeces to carry for hiking and hillwalking.
- Breathes brilliantly during high-output activities.
- Dries quickly after working hard on the trail.
- Layers effortlessly beneath waterproof and insulated jackets.

Best Fleece for Cold Weather
Norrøna Falketind Warm2 Jacket
When the temperature really starts to drop, you’ll appreciate the extra warmth that the Norrøna Falketind Warm2 Jacket brings. It’s the fleece we’d reach for on crisp winter hikes, frosty mornings and mountain days when a lightweight layer simply isn’t enough.
Compared to lighter hiking fleeces, the Warm2 offers noticeably more insulation while still remaining breathable enough for walking. It does a brilliant job of keeping you comfortable during slower-paced adventures, when you’re stopping to enjoy the view or spending more time exposed to cold winds.
It’s also an excellent layering piece. The trim fit sits comfortably beneath a waterproof shell, adding valuable warmth without feeling bulky or restrictive. That makes it a reliable choice for winter hiking, mountaineering and unpredictable mountain conditions, where staying warm is just as important as staying dry.
Although it’s designed for colder weather, it never feels overbuilt. It’s simply the fleece we’d choose when we know the forecast is calling for low temperatures and we want a layer we can depend on all day.
Why we love it
- Noticeably warmer than a typical lightweight hiking fleece.
- Perfect for winter walks and cold mountain adventures.
- Layers comfortably beneath a waterproof shell for extra protection.
- Keeps you warm during slower-paced hikes, summit stops and chilly campsite evenings.

Which Fleece Brand Is Right for You?
Every outdoor brand has its own approach to fleece design. Some focus on lightweight mountain performance, others prioritise everyday comfort, while some aim to strike a balance between the two. If you’re not sure which brand best suits your adventures, here’s a closer look at what makes Rab, Fjällräven and Montane different, along with who we think each brand is best suited to.
Rab Fleeces
Rab designs its clothing with mountain use in mind, and that comes across clearly in its fleece range. Most Rab fleeces are lightweight, breathable and easy to layer, making them a popular choice for hiking, scrambling and climbing.
Rather than feeling thick and bulky, Rab fleeces are designed to regulate your temperature while you’re on the move. Many models also use stretch fabrics, which keep them comfortable under a rucksack and don’t restrict movement on steeper terrain.
If most of your weekends are spent on the hills and you want one fleece that works across three seasons, Rab is a safe bet.
Why choose Rab?
- Lightweight mountain-focused designs.
- Excellent breathability during active use.
- Stretch fabrics for unrestricted movement.
- Easy to layer beneath waterproof jackets.
- Great for hiking, hillwalking and climbing.
Fjällräven Fleeces
Fjällräven takes a slightly different approach. While its fleeces are perfectly capable on the trail, they’re designed to be more versatile than purely technical mountain layers.
The Scandinavian brand is known for making durable clothing that looks just as good away from the mountains. Many people buy a Fjällräven fleece because it’s something they can wear on a weekend walk, while travelling or simply every day without it looking like specialist outdoor gear.
If you’re after one fleece that can do a bit of everything, Fjällräven is well worth considering.
Why choose Fjällräven?
- Comfortable for all-day wear.
- Durable construction built to last.
- Clean, understated Scandinavian styling.
- Equally suited to hiking and everyday use.
- Great for walking, travel and camping.
Montane Fleeces
Montane is all about keeping weight down without sacrificing performance. Its fleeces are aimed at people who spend long days traversing the mountains and don’t want unnecessary bulk in their packs.
They’re highly breathable, dry quickly and layer exceptionally well beneath waterproof shells. If you tend to generate plenty of heat while hiking, a Montane fleece is often a better choice than a heavier, warmer alternative.
For fast hiking, mountain days and year-round layering, Montane is one of the strongest options available.
Why choose Montane?
- Lightweight technical designs.
- Breathable and quick drying.
- Minimal bulk for easy layering.
- Ideal for fast-paced hiking.
- Great all year round.
Norrøna Fleeces
Norrøna sits at the premium end of the market, producing technical clothing designed for demanding mountain conditions. Its fleece range emphasises warmth and durability, making it a strong choice for colder weather and bigger days in the hills.
Compared to many lightweight fleeces, Norrøna models often feel more substantial, providing extra insulation without becoming overly bulky. They’re well-suited to winter hiking, mountaineering and anyone who spends time outdoors when temperatures start to fall.
If you regularly head into the mountains throughout autumn and winter, Norrøna is a brand that’s well worth the investment.
Why choose Norrøna?
- Premium technical mountain clothing.
- Warmer fleeces for colder conditions.
- Excellent durability and build quality.
- Designed for demanding mountain use.
- Ideal for winter hiking and mountaineering.
Brand Comparison
Each of these brands makes excellent fleeces, but they cater to slightly different needs. If you’re still deciding which one is right for you, this quick comparison highlights where each brand stands out. Think about how you normally spend your time outdoors, as the best choice isn’t always the warmest or the most technical, but the one that best matches your adventures.
| Brand | Best Known For | Typical Warmth | Best Choice If… |
| Rab | Technical hiking and climbing | ★★★★☆ | You want one fleece for almost every hike. |
| Fjällräven | Trekking and everyday outdoors | ★★★★☆ | You want durability and something you can wear every day. |
| Montane | Fast and light mountain days | ★★★☆☆ | You prioritise low weight and breathability. |
| Norrøna | Alpine and winter adventures | ★★★★★ | You hike in colder conditions and want maximum warmth. |
Understanding Fleece Weights
Not all fleeces are designed to do the same job. Some are made to keep you comfortable while you’re working hard uphill, while others are built to provide extra warmth when the temperature drops. Choosing the right fleece weight can make a big difference to your comfort, especially if you spend a lot of time outdoors throughout the year.
Lightweight Fleeces
Lightweight fleeces are designed for active use. They provide just enough warmth to take the chill off while allowing excess heat and moisture to escape, making them ideal when you’re constantly on the move.
They’re also excellent layering pieces. Thanks to their slim fit and low bulk, they sit comfortably beneath waterproof or insulated jackets without feeling restrictive.
Best for
- Summer hiking
- Fast-paced walks
- Trail hiking
- Layering beneath waterproof jackets
- High-output activities
Midweight Fleeces
If you’re only planning to own one fleece, a midweight model is usually the safest choice. It offers a great balance of warmth and breathability, making it suitable for most walking and hiking throughout the year.
These fleeces are warm enough for cool mornings and breezy summit stops but breathable enough to stay comfortable while you’re moving. They’re also versatile enough for everyday use, travel and camping.
Best for
- Three-season hiking
- Everyday walking
- General outdoor adventures
- Travel and camping

Heavyweight Fleeces
When winter arrives, a heavier fleece makes much more sense. These fleeces prioritise insulation over ventilation, helping you stay warm during slower-paced walks, long rest stops and cold mountain days.
While they’re generally too warm for strenuous hiking in mild conditions, they’re brilliant as part of a winter layering system beneath a waterproof shell or when you’re spending more time standing still around camp.
Best for
- Winter hiking
- Cold campsites
- Mountain adventures in low temperatures
- Summit stops
- Static warmth
