Building on the legacy of Outdoor Researchs award-winning Helium Collection, the completely revamped Mens Helium Pants take durable lightweight waterproof protection to an entirely new level. Diamond Fuse technology enables the Helium Rain to be 5x more tear-resistant than the Helium II, and an even lighter weight. Completely seam-taped, waterproof, yet still breathable and comfortable in rugged conditions, the new Helium Rain Jacket and Pants will be the first thing any hiker, peak bagger, or off-trail adventurer will pack for the most durable lightweight rain protection.
