Black Diamond Quantum 55

The ultimate blend of light weight and load-carrying ability in a technical alpine pack, the Quantum comfortably hauls heavy loads in the high peaks using our fully modular V-Flex suspension system that conforms to your back. Cushy 15 mm foam is used in the ergonomically-curved shoulder straps and 14 mm in the waistbelt with additional, stiffer foam added on pressure points for weight distribution. It’s built with ultralight, durable and water-shedding VX 21 Dimension Polyant laminated fabric and lined with lightweight 30d SilNylon. For summit pushes, alpinists can minimize the Quantum by removing the V-Flex suspension, top lid, waistbelt and crampon straps. Additional lightweight, webbing waistbelt included.
