As seen in Outside Magazine, these are the most durable and lightweight waterproof pants with Diamond Fuse technology. More durable and lightweight than ever before. The Helium Rain Jacket and Pants take durable lightweight waterproof protection to an entirely new level. Diamond Fuse technology enables the Helium Rain Kit to be 5x more tear-resistant than the award-winning Helium II Collection, 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.
