Helium - BC 23
Ultra-light backcountry performance. That’s what you demand, and that’s what the Atlas Helium-BC delivers. With the 23” model coming in under 3lbs per pair the Helium-BC is almost as light as the name implies. The composite Helium deck provides the feather-light foundation and features a unique louver design to shed snow more efficiently. The low-profile, tempered steel BC crampon sits lower in the frame to compliment the PackFlat™ binding and allow for a more natural rotation feel with every step. A backcountry necessity, this binding features urethane Z-straps that hold the foot securely and are field-serviceable with the included BC utility strap. As the name implies, it’s designed to pack down flat when not in use for easy and efficient packing or lashing. Adding to the grip of the BC crampon, anodized aluminum traction rails provide a secure grip when ascending, descending and traversing. When weight and space are limited, but reliability and performance can’t be, you need the Helium-BC
