Joseph Y. ★★★★★ Oct 20, 2026

The 15.5-micron wool is genuinely softer than any other base layer I've owned, no itch at all even against bare skin. Wore it on a freezing morning walk and the heavyweight knit held the warmth without making me feel clammy. Half zip is a nice bonus for venting when I started to heat up.

The half-zip makes layering so easy, and the 15.5-micron wool is noticeably softer against my skin than other base layers I've tried. It kept me perfectly warm on a freezing morning hike.

I live in northern Minnesota and this layer handles single-digit mornings better than any other top I’ve owned. The half zip makes it easy to dump heat without stripping layers, and the wool doesn’t itch at all against my skin.
