What Our Gearhead® Experts Are Saying: "I use the Dryflx Beanie for early runs or night rides because it breathes incredibly well and the reflectivity really stands out. The seamless construction makes it super comfortable under a helmet, and it dries fast enough that I never feel chilled afterward. It’s lightweight but surprisingly warm for active days." We grab the Buff Dryflx Beanie when our high-output adventures call for lightweight warmth and total freedom of movement. The seamless DryFlx knit stretches effortlessly in every direction and keeps us dry with quick-drying performance that lasts through intense efforts. Its low-profile design fits smoothly under running or cycling helmets, and the 360° reflective detailing boosts visibility on dim trails, early-morning commutes, or twilight training sessions. Made with 71% recycled materials, this beanie blends sustainability and function in a breathable, ultralight layer built for active days in any season.
