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, Patagonia's 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. Their fine merino wool is from the grasslands of Patagonia. They 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.
