This "Outdoor T-shirt" is made from a jersey fabric knitted with 20-count cotton-polyester open-end yarn. While the fabric is sturdy enough to live up to its "outdoor" name, it also features a moisture-wicking and quick-drying finish, so it absorbs sweat and dries quickly. The dry, rugged texture characteristic of open-end yarn is also perfect for the outdoors. It even has Pocket for small items.
