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.

Voted Best Lightweight Rain Jacket by Inside Hook, the Helium Rain Jacket is more durable and lightweight than ever before. 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.
