Hazel ★★★★★ Oct 21, 2026

This thing is a beast for cold mornings—the 400g weight is substantial without being stiff. Wore it as a base layer hiking in 20-degree weather and stayed bone dry.

James D. ★★★★★ Oct 20, 2026

The 400g merino wool feels noticeably substantial without being itchy at all, and the half-zip makes layering or venting really easy during cold morning hikes. It’s become my go-to for everything from base layer duty to just wearing around the house.

Joseph ★★★★★ Oct 19, 2026

The half-zip sits perfectly under my shell without bunching up, and the 400g weight is substantial enough that I’ve worn it alone on chilly evenings. It’s been my daily layer for two weeks of wet weather and there’s no stink at all, which sold me on merino.
