The short-sleeve version of our lightest merino baselayer features an ultralight merino wool blend that regulates temperature to help you stay comfortable through changing conditions and activity levels, and it naturally resists odor to suppress your scent. We designed this short-sleeve crew with ArmorSpun merino wool to give it the extra durability needed to last.
