Building on the legacy of the award-winning Helium Collection, the Helium Rain Pants take durable, lightweight, waterproof protection to a new level. Pertex® Shield with Diamond Fuse Technology makes the Helium Rain Pants 5x more tear-resistant than the previous Helium II model and even lighter weight. The diamond-shaped filaments make the fabric highly breathable and windproof, and the fully seam-taped construction seals out the elements. Elastic cuffs with gripper tape and a carabiner loop provide convenient storage options, the crotch gusset provides full range of motion, and the reflective logo enhances low-light visibility.
Completely waterproof yet breathable and comfortable in adverse conditions, the new Helium Rain Pants should be the first thing any hiker, peak bagger, or off-trail adventurer packs for durable, lightweight rain protection.
Note: We recommend the Helium Rain Pants be cleaned regularly with Nikwax Tech Wash to maintain water repellency.
