Function and throwback fashion in one fine-looking hat. The 40th Anniversary Class V Hat is made from lightweight, quick-drying nylon, making it perfect for the river, the trail, or anywhere else your adventures may take you. Throw in some classic retro style with the pinch front 5-panel design and 5mm rope detailing, mix it with some slick 40th anniversary graphics and subtle woven label detailing, and you've got a limited-edition hat that you'll never want to take off.
