Smartwool Active Fleece Wind 1/2-Zip Jacket - Men's Black, S

What Our Gearhead(R) Experts Are Saying: "This is my go-to pullover for cold, windy runs or hikes.

The merino interior is soft and warm, but the windproof front panel makes the biggest difference-no icy gusts cutting through.

The stretch lets me move freely, and the thumbholes keep it in place when layering." The Smartwool Active Fleece Wind 1/2-Zip Jacket is built for high-output adventures in unpredictable conditions.

A windproof front panel with a non-PFC DWR finish shields us from icy gusts and light precipitation, while the 4-way stretch knit allows us to move freely and comfortably.

Inside, a soft-brushed merino layer sits against the skin, wicking moisture and adding natural warmth without bulk.

Reflective details keep us visible during low-light starts or evening finishes, while thoughtful features like a secure chest pocket and thumbholes add practical comfort.

With its regular fit, it layers easily over a base or under a shell, giving us a versatile piece for shoulder-season running, winter hikes, or blustery ski tours.

A balance of protection, comfort, and mobility, the Active Fleece Wind 1/2-Zip proves itself as a reliable layer when the weather turns.
