The Patagonia Terrebonne Hat is built from recycled polyester fabric with exceptional breathability and abrasion resistance and treated with a durable water repellent (DWR) finish made without intentionally added PFAS to resist moisture with breathable fabric (40 CFM), and the front-panel structure allows excess heat to escape quickly, and the unstructured, mid-crown design lets the hat mold to the head for a snug fit. This brim stiffener is made with NetPlus 100% recycled fishing nets. It has a lightweight, adjustable closure with an elastic anchor for a snug, active fit and a minimal sweatband with a wicking finish for moisture and temperature management. Made in a Fair Trade Certified factory, which means the people who made this product earned a premium for labor.
