Constructed from ultrafine heavyweight 400-gram wool, it naturally wicks away sweat and resists odors effectively. Features a short collar and a half-zip front to effectively regulate your temperature.

Victoria X. ★★★★★ Oct 21, 2026

I’ve been using this as my go-to base layer for cold-weather runs, and the moisture-wicking really keeps me dry even when I start sweating. The 400g weight feels substantial without being bulky, and the half-zip makes layering a breeze.

Ellie ★★★★★ Oct 20, 2026

Wore this on a freezing morning hike and stayed bone-dry the whole time, the moisture-wicking really does its job. The half-zip makes it easy to dump heat without fully stripping layers, and 400g feels like a proper winter shield against the wind. Perfect for throwing on as a light sweater too.

Pulled this on for a hike in near-freezing temps and stayed warm without overheating once I started climbing. The half-zip is perfect for dumping heat on the go.
