Put it on and forget about it. The Ultralightweight Ridge Hat prioritizes breathability and comfort for your sweatiest, highest-intensity activities. The 100% recycled polyester fabric has laser-perforated holes so heat can easily escape, and the lightweight, flexible brim packs down small so you can stow it in your pocket when needed. Made in a Fair Trade Certified factory. | Patagonia Ultralightweight Ridge Hat - Packable Hat in Black - Outdoor Hats - Polyester
