This luxurious yet hardworking shirt has the soft, lazy feel of an afternoon under a desert cottonwood, even when your day is anything but peaceful. It's made of Merino Daily, our regular fit, everyday Merino baselayer 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 responsibly 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.
