Feels as easy as a cold one at the end of a hot day. Merino Daily is our regular fit, everyday Merino baselayer, made for all-day comfort and easy care. Merino wool is naturally breathable, regulates body temperature and stretches. It's also wonderfully soft and naturally resists odor. Our fine merino wool is sourced from the grasslands of Patagonia. We slow-wash it for softness and shrink resistance, without the use of chlorine, then blend it with 48% Capilene polyester (100% recycled) for durability, quick dry times and moisture transfer superior to that of 100% merino. Features include a self-fabric collar for chafe-free comfort and full underarm gussets for unhindered shoulder mobility.
