A new approach to sport caps. Combining style and performance, this ultralight cap is designed for outdoor activities like trail running, hiking and trekking. The Pack Run Cap offers outstanding protection against the sun and a great sweat management system. On top of it all, it packs into a tiny ball without losing its original shape once released. Designed for the high performance accessories seeker, the pack concept by BUFF® is the base of our most technical caps and visors. Developed in our design labs and fully tested by top BUFF® ambassadors, our packable designs can be folded inside a hand, twisted and packed into the smallest pocket without losing its shape once released.
