Natalie A. ★★★★★ Oct 22, 2026

Put this on over a thin tee for a chilly morning run and never felt overheated, the merino wool breathes really well without getting clammy. The sleeves are just long enough for my arms and the collar lies flat under a jacket.

Avery I. ★★★★★ Oct 21, 2026

The quarter-zip collar sits at just the right height so I can zip up fully for cold mornings or open it to cool down. I’ve worn it hiking and commuting—it breathes well and doesn’t itch at all.

The 100% merino wool is incredibly soft against my skin, and the collar height is just right to keep me warm without feeling choked. On a chilly morning hike, this base layer let me regulate my temperature perfectly when I unzipped it a bit.
