Ultralight and packable, the Helium UL Jacket offers waterproof protection for fast missions
What Our Gearhead® Experts Are Saying:
"I bring the Helium UL Jacket on every trip where weight matters but storms are still on the table. It disappears into my pack until I need it—then delivers full waterproof protection in seconds. The hood stays put in wind, and the entire jacket stuffs into its own pocket so it's never in the way."
When we're racing against weather or moving fast in the alpine, we don’t compromise on protection or weight. The Outdoor Research Helium UL Jacket packs down to the size of a granola bar and weighs next to nothing, yet it still delivers full waterproof, windproof performance when the skies open up.
Its minimalist build hides an impressive feature set: a fully seam-taped Toray shell with breathable 2.75L waterproofing, an adjustable hood with brim wire for visibility, and shaped cuffs that seal out gusts. Thoughtful design touches—like reflective logos and the stuff-sack pocket—keep it adventure-ready from summit pushes to far-flung travel.
