John ★★★★★

Wore this on a three-day hike and it never got that gross funk synthetic tees usually pick up by day two. The merino blend breathes well on climbs and still feels soft against the skin.

Steven P. ★★★★★

The merino blend is the real deal here — no itch at all, and it stayed odor-free through three days of climbing and one very questionable hostel sink wash. Fit is trim without being tight across the shoulders.

William ★★★★★

Wore this on a two-day hike and it never got clammy or smelly, which says a lot for a wool tee. The merino blend feels soft against the skin and dries fast after a quick rinse.
