Men's Active Fleece 1/2 Zip

Four-way stretch knit fabric puts soft-brushed Merino blend next to skin and recycled synthetic material against the elements to help balance comfort and protection. The interior face runs a brushed Merino-recycled-polyester-elastane blend (38% Merino in the main body) that traps body heat and manages moisture against the skin; the exterior face is a recycled synthetic knit that handles abrasion and shape retention on the outer surface. The two faces are knit as one fabric rather than layered separately — no separate liner pulled over a shell, no bunched layers between them, no cold spots where air gets between the layers. (Note: this is the same construction as the SW003259 Men’s Active Fleece Jacket in this family — both rely on the same two-face Merino-interior/recycled-synthetic-exterior knit, but the 1/2 Zip styling offers a different layering interface than the full-zip Jacket.)

Soft-brushed Merino blend next to skin (38% Merino Wool in the main body) delivers the natural temperature regulation and odor resistance Merino is known for — the 1/2 Zip stays comfortable across the cold-to-warm swings of a long cold-weather workout without the clammy chill a pure synthetic would develop when you stop moving. Merino’s natural odor resistance means the 1/2 Zip stays fresh across multi-workout days between washes.

The recycled synthetic exterior handles the abrasion and shape retention the 1/2 Zip’s outer surface sees — pack-strap contact on a backcountry day, repeated wear under a shell, the rough use a mid-layer takes as a daily training piece. The 54% Recycled Polyester in the main body keeps the durability performance with a lower-impact material choice than virgin synthetic.

Four-way stretch knit fabric allows for maximum mobility — the stretch is knit into the fabric itself rather than added as spandex panels at the side seams. The four-way stretch moves with the body through running, climbing, skiing, and training movement without the binding a less-stretchy fleece would create at the shoulder or elbow. The fabric recovers its shape after the movement stops, so the 1/2 Zip doesn’t bag out at the elbows or sag at the hem over time. The 8% Elastane content is the same stretch level as the SW003259 Men’s Active Fleece Jacket and the SW003262 Women’s Active Fleece Jacket in this family.

The 1/2 zip front allows venting on the uphills and full coverage on the chairlift — the zipper pulls down for high-output climbs and back up for the cold chairlift ride or windy ridge walk. The 1/2 zip is the right tool for stop-and-go cold-weather activity where the body’s heat output fluctuates rapidly between the cold chairlift and the high-output descent. The 1/2 zip styling distinguishes this piece from the full-zip SW003259 Men’s Active Fleece Jacket in the same family.

The soft-brushed Merino blend fabric runs soft against the skin — no itch, no scratch, no rough texture to interfere with the next-to-skin comfort a cold-weather mid-layer needs to deliver across a full day of wear. The Merino blend’s brushed interior face creates the cozy next-to-skin feel the description calls out, while the recycled synthetic exterior face handles the abrasion and shape retention the outer surface sees. The two-face construction is what makes the brushed interior face possible without compromising the exterior’s durability.

The Merino blend fabric helps balance comfort and protection from the elements — the balance the description explicitly calls out. Merino handles the comfort side (natural moisture management, natural odor resistance, natural temperature regulation, soft-brushed next-to-skin feel) while the recycled synthetic exterior handles the protection side (abrasion resistance, shape retention, weather-facing durability). The balance is what makes the Active Fleece 1/2 Zip the right tool for the cold-weather workout use the description positions.

The pocket bag is 100% Recycled Polyester — a recycled-content pocket construction that handles the essentials (a phone, a key, a card, a pair of liner gloves) without the bulk a heavier pocket bag would add. The recycled polyester content keeps the pocket’s durability performance with a lower-impact material choice. (Note: the description doesn’t explicitly call out pocket positions, but the construction includes a pocket bag spec that suggests standard hand-pocket storage in line with the SW003259 Men’s Active Fleece Jacket.)

The fit is cut to a regular fit — similar to the SW003259 Men’s Active Fleece Jacket, the regular fit is intended to give you room to move without additional bulk. The cut leaves space for a base layer underneath without the binding a tight athletic fit would create at the chest and shoulder, and layers cleanly under a shell or a ski jacket without the bulk an oversized fleece would create. The regular fit works on its own for cold-weather training in milder conditions.

Built for the cold-weather active uses where a Merino-blend fleece mid-layer is the right tool — cold-weather training, shoulder-season running, hiking, climbing, après-ski, and everyday cold-weather wear. The Merino interior handles the sweat and the cold-to-warm swings; the recycled synthetic exterior handles the abrasion of daily wear and pack-strap contact; the four-way stretch handles the active movement; the 1/2 zip handles the vent control across the wide temperature range of a cold-weather workout.
