Sebastian ★★★★★ Oct 20, 2026

The weight is perfect for layering under my shell on cold morning hikes without feeling bulky. The moisture-wicking fabric kept me dry even when I started sweating on the uphill sections.

Chloe G. ★★★★★ Oct 19, 2026

Finally found a wool base layer that doesn’t itch at all against my skin, even after a full day of hiking. The 400g weight is perfect for keeping me warm under a shell without feeling bulky, and the half-zip makes layering a breeze.

I wear this as my go-to mid-layer when ice climbing and it handles sweat way better than my old synthetic. The half-zip makes it easy to dump heat without taking my shell off.
