The Women's Kryptek Icon Tech Shirt is a technological mid-layer mock neck top - for all the necessary dirty work. Durable Poly knit with moisture transport is used to keep you comfortable, with an added mesh vent at lower back for temperature regulation. Stain release technology has been added as well, to keep the blood or any other stains at bay, and anti-microbial technology keeps you from smelling like your catch. The last touch was to add a small amount of spandex to make sure none of your movement is restricted. Cooling technology works to keep you comfortable under the sun with SPF/UPF to keep you protected. This is the piece of equipment you won't leave home without. Body: 90% polyester; 10% spandex; Mesh Back: 100% polyester. Imported.
