Ultralight backcountry performance. That's what you demand, and that's what the Atlas Helium-BC delivers. Weighing in at under 3 pounds per pair, the Helium-BC is nearly as light as its name suggests. The Helium composite deck forms the featherlight foundation and features a unique lamella design that efficiently sheds snow. The low-profile BC crampon made of hardened steel sits deeper in the frame to complement the PackFlat binding, allowing for a more natural pivot feel with each step. The binding is essential in the backcountry and features urethane Z-straps that securely hold the foot and can be maintained on-site with the included BC utility strap. As the name implies, the binding packs flat when not in use for easy and efficient storage or strapping. The anodized aluminum traction rails provide additional grip for both ascents and descents, as well as traversing. When weight and space are limited, but reliability and performance are not, you need the Helium-BC. Available sizes: Unisex 23", 26". Weight per pair: 3.19 lbs / 1.45 kgs (26"). Surface area: 175 sq in. Features: - Helium deck - PackFlat binding - Helium BC crampon - Aluminum traction rails - 19° heel lift.
