Inspired by ultrarunners, the signature Patagonia Duckbill Cap is ready for all running adventures. This cap features a lightweight, breathable design that will keep runners cool and comfortable for the miles ahead. Additionally, with a miDori bioSoft headband, PVC-free DWR finish, and HeiQ® Pure odor control, the Duckbill Cap will keep moisture at bay, allowing runners to fully immerse themselves in their run. As an added benefit, this cap utilizes a packable foam brim construction that allows runs to easily pack the cap away without fear of compromising the integrity of the hat.
