Built with bluesign® approved nylon, it packs UPF 50+ protection into a breathable, quick-drying, water-resistant fabric that keeps sweat and splash under control. An updated brim design gives you extra coverage—3.3" at the back, 2.5" up front—while a crown cinch and detachable chin cord keep it secure when the wind picks up. And when the clouds finally roll in, it packs away in its own interior stow pocket until the sun shows up again.
