Outdoor Research Helium Rain Jacket for Women

Our most durable and lightweight waterproof jacket powered by Diamond Fuse technology, iconic for its streamlined design that packs down to the size of your palm.

Durable lightweight storm protection powered by Diamond Fuse technology.
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.

Technology

Diamond Fuse

Durability. Strength. Lightweight.
Pertex developed Diamond Fuse technology as a unique way of improving the durability and abrasion resistance of fabrics without adding any unnecessary weight. Diamond Fuse fabrics use yarns with unique diamond shaped filaments that lock together to create a durable and highly abrasion resistant fabric. This engineered structure allows Diamond Fuse fabrics to remain very stable over extended wear and washing.
