The Outdoor Research Drifter Cap is made of Gore-Tex PacLite fabric, fully seam taped for waterproof and breathable protection. A shaped, plastic-stiffened bill sheds precipitation and blocks glare during unexpected sun breaks. The fitted, 6-panel design offers a close, wind-resistant fit. An external drawcord adjustment offers security when sudden squalls try to bare your head. Paddle through rain-dappled waters with the Outdoor Research Drifter Cap.
