Made of 100% polyester (87% recycled) plain-weave fabric with exceptional breathability and abrasion resistance; microtexture creates excellent next-to-skin comfort; a DWR (durable water repellent) finish resists moisture. The unprecedented air permeability (40CFM) of the fabric and the breathable front-panel structure allow excess heat to escape quickly. The soft brim has an EVA insert for next-to-forehead comfort. The brim is made of 100% recycled fishing nets. The lightweight Velcro® closure includes an elastic anchor for snug active fit. The lightweight, low-profile sweatband is made from our 100% recycled Capilene® Cool Trail fabric for moisture and temperature management; it also has built-in HeiQ® Fresh durable odor control. Fair Trade Certified™ sewn, which means the people who made it earned a premium for their labor.
