The iconic, award-winning Helium Rain Jacket is a lightweight, ultra-packable outdoor essential. Pertex® Shield Diamond Fuse 2.5-layer fabric delivers rugged durability that breathes as your pace quickens while fully taped seams keep moisture and wind at bay on gusty ridges or drizzly descents. Reflective chest logo and forearm overlays increase visibility in low-light environments, and the jacket stuffs into its chest pocket (hand pocket for W’s) for quick stowage in your pack. Elastic wrist cuffs and a drawcord hem deliver a tailored fit that layers comfortably under a pack hip belt during long days on trail.
