Built for performance, weather protection, breathability and stuff-away compressibility, the five-panel Airdini Cap folds down so small it fits into the pocket of our Strider Pro Shorts. Airshed fabric on the side panels dries fast and breathes freely, while Houdini fabric on the brim and body sheds moisture and variable weather. There's a minimal sweatband and a stretchy back stretch panel that acts as stash pocket for key or card and also converts to stuffsack with clip-in. With a reflective logo and a DWR (durable water repellent) finish on the body and brim. It's also Fair Trade Certified sewn, which means the people who made it earned a premium for their labor.
