The Kids' Patagonia Capilene Silkweight T-Shirt is made from stretchy 84% recycled polyester and 16% spandex jersey fabric. The crewneck lies close to the neck for better coverage, while rolled-forward shoulder seams prevent chafing under backpack straps. Underarm gusset panels keep the shirt from pulling up, allowing comfortable mobility. A slight drop-tail hem offers extra coverage, and a locker loop on the interior neckline makes it easy to hang dry.
