First came the Adventure Hat, then the Ultra Adventure Hat, and now…introducing the Ultra Adventure Storm Hat: what we like to call the world’s best rain hat. Featuring 100% waterproof seam-sealing technology, this hat is easy to fold, stash in your pack, and perfect for backpacking or hiking in the rain! The Ultra Adventure Storm Hat breathes, fits comfortably, and has a chin strap so it stays put in high winds. Wherever your adventures take you, this hat will keep you dry. Guaranteed.

Adjustable Sizing

Pick your size, then fine-tune the fit with this one-handed size adjuster.

Reflective Details

With reduced visibility and shorter days, safety and reflectivity are non-negotiable details for cool-weather adventure. Our waterproof styles offer reflective trims and practical details for everyday adventures like running at dusk or heading out for an early morning walk.

Folding Brim

Wear it on your head. Stick it in your pocket. Our amazing, space-saving, folding Clamshell Brim and patented Reverse Split Brim are engineered for life by the seat of your pants.

PFC-Free Durable Water Repellent

DWR coating helps water bead up and roll off fabric. This season we've transitioned the majority of our performance styles to a lower-impact formula to ensure safety for factory workers, customers, and the environment.
