Considered a PCT favorite, The Trek featured the Helium Rain as the most durable, ultralight rain jacket for backpacking in 2021. 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.
