Outdoor Research Helium UL Jacket - Men's

Helium UL Jacket delivers ultralight, packable waterproof protection for alpine and trail missions

What Our Gearhead® Experts Are Saying:

"The Helium UL Jacket is in my pack 100% of the time. It’s so light I forget it's there, but it delivers serious waterproof protection when weather hits. It’s perfect for fast trail days, summit pushes, or travel—plus it stuffs into its own pocket."

We chase summits and move fast through variable terrain—and the Outdoor Research Helium UL Jacket is our essential layer for when the skies change faster than our pace. Designed for minimalist missions and ultralight packing, this jacket delivers reliable waterproof and windproof protection without weighing us down.

The Toray 2.75-layer shell keeps moisture out while remaining breathable, and every detail is tuned for efficiency: a brimmed, adjustable hood for storm visibility, a stuff-sack chest pocket for easy stowage, and shaped cuffs that seal out gusts. At just 5.7 ounces, the Helium UL disappears into our pack—until the storm rolls in and we’re grateful we brought it.
