To bring you the best fleece jacket review, we first selected the top-selling and highest-rated models out there. We focused on technical models designed for active use in the outdoors and also tested a few non-technical options. We've tested all the way from the cold climates of Canada to the warm deserts of Nevada and many places in between. We rated each on six different metrics, assigning scores based on both subjective and objective performance. Each fleece was worn for at least three months, with some being continually tested over the years. Many women test each jacket, with our main tester gathering data and providing you with our results.
Warmth
This test is simple. After evaluating the materials, fabrics, and features, we wear each in cold weather. We wear them on their own and in a layered system, noting which option provides the best overall warmth.
Water resistance is a big part of warmth, because if you can't stay dry, you won't be able to stay warm as soon as you come to rest. To test water resistance, we spritz each fleece to see how long it takes the fabric to absorb the water. When we can't find a mountain to climb (which is hardly ever), we simply layer up with a thin base layer and stand outside in windy, rainy conditions to see how well the jacket protects us.
Comfort
Comfort and coziness are key to wear all day. We look at the plushness and thickness of fabrics, note great features (like thumb loops), and wear each for many days. We note any odd areas of fit and how the fleece feels for wearing many days on end. We also sleep and lounge in each one to see which our testing team prefers.
We also take the time to climb, hike, and move in each one. We note if the fleece moves with the body or stays rigid, requiring constant adjustments while tackling adventures.
Breathability
We snowboard, hike, bike, and run in each of these fleeces. We also look at the fabric composition and porosity to determine which offers the best and worst in breathability. They are testing in both a layered system and on their own.
Layering Ability
We simply layer clothes over and under! We try each fleece with many different types of base layers and jackets. We also look at the relative friction of face fabrics, which are smooth and which are rough.
Weight
The first test is simple: we pull these jackets out of the package and put them on a scale to measure their weight. We then take the time to push, shove, and zip each fleece to see how small we can get it to pack down. We note their compressed size, and we travel with every jacket – whether that's in a carry on or in a daypack – to gauge their overall packability.
