Ultralight Waterproof Protection for Hiking and Travel The Helium UL Pant is built for fast and light hiking and unpredictable weather, delivering ultralight, waterproof protection for minimalists who move quickly in the mountains. Constructed with Toray Dermizax 2.75-layer fabric, these pants are fully waterproof, windproof, and breathable for comfort in wet, windy conditions. The 15D ripstop nylon shell is exceptionally lightweight yet durable, and the back pocket doubles as a stuff sack for compact storage. Functional details include ankle zippers, elastic cuffs with gripper tape, and lace loops for secure fit, while a gusseted crotch and elastic waistband with drawcord provide mobility and comfort. Reflective logos add visibility in low light for confidence in any conditions.
