A hat that’s your companion on demanding mountain runs and long, multi-day adventures needs to be as packable as possible. That’s why we’ve given the Rab Boonie Hat a soft brim and a foldable 5-panel design, so you can tuck it into your running vest or keep it stashed away in your backpack, ready to pull out when the heat hits. Engineered with a combination of lightweight, wicking fabrics including a venting mesh crown, this boonie-style hat is crucial to keeping a cool head when you’re moving at pace in hot climates.
