Climb, run, and hike in this naturally light and odour-fighting Merino tee.This Merino-blend tee is an essential first layer for mountain runs, climbs, and approaches all year long. Naturally great at regulating temperature and anti-bacterial, Merino wool resists pilling and odours making it an excellent (less stinky) layer for multi-day pitches and hikes. Trust us, your tent-mates will thank you. What's been updated: Updated Betaspun Merino wool combines nylon and TENCEL™ fibres for a lighter, softer, more durable yarn that regulates temperature and resists abrasion and pilling. We also gave it a new closer-to-body fit with a shorter body and straight hem.
