Sebastian ★★★★★ Oct 21, 2026

This is my go-to for winter trail runs now. The half zip lets me cool down fast when I start sweating, and the merino wool doesn't itch against my skin like other base layers I've tried.

Ava Z. ★★★★★ Oct 20, 2026

I’ve been reaching for this top every cold morning run—the merino wool somehow keeps me warm without that clammy feeling, even when I’m working hard. The half zip lets me crack it open just a bit when I need airflow, and the fit is snug but never restrictive.

The half zip makes it easy to vent heat during a tough hike, and the merino wool didn't itch at all against my skin. It kept me warm without overheating, even when I was working hard.
