"Backcountry Gearhead® Recommendation: ""This is my go-to layer for early morning hikes or cool camp nights. It’s light, soft, and breathes way better than a traditional fleece. The half-zip makes it easy to dump heat fast, and the thumbholes are perfect for layering under a shell when temps drop. It’s a small piece that does a lot of work."" We reach for the Fjallraven Abisko Day Hike 1/2-Zip Top when cool mornings and breezy ridgelines call for just a touch of extra warmth. Made entirely from recycled polyester, this lightweight fleece wicks moisture and dries quickly to keep us comfortable on the move. The half-zip design offers easy ventilation, while the soft, smooth texture feels great next to the skin—whether layered under a shell or worn solo on the trail. Discreet thumbholes keep sleeves in place and add warmth when the air turns crisp. Dyed using Fjallraven’s closed-loop CO2 process, this top is as gentle on the planet as it is comfortable to wear. From sunrise summits to campfire lounging, it’s a dependable layer that moves effortlessly between seasons."
