The ExOfficio Mens Reef Runner Long-Sleeve Shirt is designed with the adventurer in mind, combining the style you want and the performance you need. The quick-drying shirt is made with bluesign-approved lightweight polyester fabric. Its mesh-lined side panels keep you cool in the most punishing heat, and the UPF-30 rating protects from harmful UV rays, meaning longer hikes or more time fishing at your favorite spot. A utility loop at the front left can be used to keep your rod securely fastened or your sunglasses within reach. Two zippered chest pockets safely stow your valuables, and a drop-in gadget pocket at the left side keeps gear within reach.
