How to Choose a Fleece Jacket

Updated June 2026Independently researchedNo paid placement.

What's the difference between a fleece jacket and a polar fleece pullover?

A fleece jacket usually has a full front zipper, making it easy to layer and vent heat. A polar fleece pullover slips over your head with a partial zip (or none at all) and often feels cleaner under a shell. Both use the same fluffy polyester knit, but a pullover is lighter (no zipper weight) and packs smaller, while a zippered jacket gives you more temperature control and is easier to take on and off. Your choice comes down to how you’ll use it: if you need quick ventilation on a hike or frequent layers for commuting, go with a jacket. If you want a simple, cozy mid-layer for skiing or around-town wear, a pullover does the job with less bulk.

How do I choose the right fleece weight?

Fleece weights are broadly grouped into light, mid, and heavy. Lightweight fleece (often called micro fleece) is thin, stretchy, and ideal as a base layer under a rain jacket or for cool-weather runs. Mid-weight fleece (the classic 100-weight fleece) is the most versatile, warm enough for a chilly morning stand-alone but still breathable enough for active use. Heavyweight fleece (often 200-weight or expedition weight) is thick, plush, and designed for low-output activities in freezing temperatures, like belaying at a crag or sitting around a campfire. Don’t overthink it: if you’ll be moving a lot, lean toward mid-weight or lighter. If you run cold or want a single jacket for winter walks, a heavyweight is a better bet.

What features should I look for in a fleece jacket?

Pockets are the first detail to check. Zippered hand pockets keep your phone and keys secure on the trail, while two chest pockets (one zip, one flap) give more storage and break up the look. A high collar or stand-up collar blocks wind, and a drawcord hem lets you trap warmth. Cuffs matter too: elastic cuffs seal better than a simple hem, and some jackets have thumb loops for layering. If you plan to wear the fleece in rain or light snow, look for a water-repellent finish (usually DWR). it won’t make the fleece waterproof, but it helps beads shed off. And if you’ll be in high winds, a fleece with a tighter knit or a windproof panel behind the zipper will keep you much warmer.

How should a fleece jacket fit for layering?

A good fleece fit depends on your layering system. If you’ll wear it as a mid-layer under a hardshell, you want a slim or athletic fit that doesn’t bunch under your arms or around the shoulders. If it’s your outer layer for fair weather, a relaxed or regular fit gives you room for a thin base layer underneath and feels more comfortable on its own. Pay attention to sleeve length: your wrists should stay covered when you raise your arms, and the hem should sit at your hips or just below your belt line. Too short and it’ll ride up; too long and it’ll trap heat you don’t want. Many brands offer tall sizes, which are worth it if you have a longer torso.

Can I wear a fleece for winter hiking or running?

Yes, but you’ll likely need to manage layers and activity level. For high-output hiking or trail running in temps around freezing, a lightweight fleece worn over a thin baselayer is often enough, it breathes well and dries fast if you sweat. For low-output winter hiking (slow pace or stopping for lunch), a mid-weight fleece under a shell gives you warmth without overheating when you’re moving. Heavy fleece is too hot for sustained aerobic activity except in very cold (below 20°F) conditions. The key is to pick a weight that matches your output: if you’re a brisk hiker, you’ll be surprised how much warmth a simple lightweight fleece provides.

How do I care for fleece so it lasts?

Fleece is easy to ruin and just as easy to maintain. Wash it inside out in cold water on a gentle cycle, and never use fabric softener, it clogs the fibers and ruins breathability. Use a front-loading machine if possible, because top-loaders with an agitator create friction that causes pilling. Dry on low heat or air dry; high heat can melt the polyester and turn a soft fleece stiff. To minimize pilling, turn the fleece inside out before washing, and avoid washing it with heavy items like denim or towels that rub against it. If pilling does happen, a fabric shaver works wonders, or you can carefully remove pills with a disposable razor.
