Expanding on the best-selling durable lightweight collection, the Helium Wind Cap rounds out its category as minimalist cap reinforced with Diamond Fuse technology. This piece is perfect for the ounce-counting ultra runner who needs a hat that will dry on the move, and stuffs away small.

It's even designed to crush down to the size of the pocket in its cousin product - the Helium Wind Hoodie. Two other favorite features include a 360-degree sweatband made with self-cooling ActiveIce™ technology, and a rear shock cord that can be adjusted for size with a single hand on the run.
