How We Tested Fleece Jackets for Men

Friday November 17, 2023

After extensive research, we select the most promising fleece jackets and test them in the wild. We then bring them into the lab for more objective tests in controlled environments. We put each model through its paces, wearing them while skiing, climbing, backpacking, and just walking the dog around the block. Our testers assessed these jackets while wearing them in a variety of climates, from the Rockies to the Sierra Nevada, and all the way over to New England.

We tested each jacket side-by-side and then compared the results. After our testing phase, we rated each model based on their performance in five different categories: warmth, comfort, breathability, layering ability, and weight.

Warmth


We assess warmth by hiking, running, scrambling, and climbing in various weather. From warm, sunny days to cold, rainy nights, we wore each fleece during early morning scrambles, late evening hikes, and afternoons heading to the gym. We hiked hard uphill and then made casual downhill strolls during windy evenings, foggy afternoons, and rainy mornings. Indoors, we also measured each jacket's level of heat retention by tracking how long it took water to cool when tucked in the sleeve of the jacket. We also took a high-powered fan to judge the fleece's ability to withstand wind gusts.

Comfort


To evaluate the fit and comfort of each model, we noted how each fleece feels on the body. We compare the fit and feel when brand new and after a reasonable break-in period. We noted any irregularities in the material, the patterning, or the features like zippers, hoods, and pockets and how they felt against the skin and while in use. We also assessed mobility, stretching, reaching, and bending to note any areas where the fabric was too loose and bunchy, or too tight and restrictive.

Blended materials that include spandex or elastane make for a super stretchy, super mobile fleece, like the REI Hyperaxis 2.0.

Breathability


For our breathability scores, we ran up hills, skinned up mountains, climbed long routes, bouldered with friends, and took long walks. We paid close attention to the moisture-wicking ability of the material and the fleece's design for how well the piece breathed. For controlled testing, we walked the same incline for a set period and time how long it took to cool down while wearing each jacket.

The grid pattern of the Pierogi Hoody has lots of "streets" and "avenues" that facilitate breathability and air flow through the jacket.

Layering Ability


To understand the capacity of each jacket to layer well with others, we tried each fleece over a long-sleeve base layer, over and under a second fleece, and under a waterproof shell and puffy jacket. We tested how well they moved while running, skiing, and climbing to determine if each garment bunched uncomfortably in any way. We ranked how well each garment functioned individually and paired with other pieces.

Weight


This one is pretty straightforward. We pulled out our scale and weighed each model. We also assessed the packed volume of each jacket by putting them in a container of known volume, and judged how well they packed down into a backpack during field testing.
