Huk® Performance Bass Navy Long Sleeve T-Shirt. We use a durable Poly knit with moisture transport to keep you comfortable, with an added stain release to keep the blood or other stains at bay, and anti-microbial to keep you from smelling like your catch. Our last touch was to add a small of amount of spandex to make sure none of your movement is restricted. Our cooling technology works to keep you comfortable under the sun with SPF to keep you protected. Use this to layer, or by wear itself, you may have just found your best fishing buddy.
