The Men's SITKA Jetstream Vest is designed to shield you from the elements. With WINDSTOPPER® by GORE-TEX LABS, this vest completely blocks winds while remaining highly breathable to keep you dry. Wrapped in a tough softshell fabric, this vest includes reinforced panels in high-wear areas to easily stand up to the thickest brush and roughest rock. Complete with a recycled fleece backer for low-bulk warmth and knit fleece panels at the lower torso to enhance layering comfort, the SITKA Jetstream Vest is built to handle the absolute worst of the weather.
