OR's most durable lightweight waterproof shell

Building on the legacy of OR's award-winning Helium Collection, the completely revamped Helium Rain Jacket takes 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 Helium Rain Jacket will be the first thing any hiker, peak bagger, or off-trail adventurer will pack for the most durable lightweight rain protection.
