Description
The Quantum, part of Black Diamond’s Ultra Series, is designed for “when weight and speed matter most.” With a modular V-Flex suspension and removable V-Flex stay, the Quantum is engineered to haul large loads when accessing climbs or cleaning camps. In steep terrain or for summit pushes it can be stripped down to a two-pound (900 grams) climbing pack.
The Quantum features a 20 mm thick, dual-density waistbelt, cut to allow high steps through boulder fields and glacial debris. The waistbelt, with Ice Clipper slots, is easily removed for access to a harness or gear loops. Dual-density shoulder straps, 15 mm thick, are cut to provide a full range of motion. The hydration-compatible pack has a removable top lid with helmet holder, side-panel zipper access, crampon pocket, ski slots, removable bivy pad, and ice tool PickPockets. The retractable rope strap can carry several lengths of fixed ropes or two dynamic ropes, side compression straps fit sleeping pads or an alpine tent, and upper ax loops double as emergency haul loops when used with the grab loop. The Quantum comes in three sizes: 65 L, 55 L, and 45 L.

"Free Shipping. Black Diamond 45 L Quantum Pack (Fall 2008) - Backbacker Magazine Best for Climbing Award 2007 The Quantum Pack by Black Diamond has been exhaustively engineered to create a new level of performance in the big mountains. When hauling large loads to access climbs or cleaning camps, the modular V-Flex suspension provides the carrying comfort and performance of a backpacking pack. In steep terrain or for summit pushes it can be stripped down to a mere 900 grams (two pounds), making it a uncompromised climbing pack. Dual-density shoulder straps are a supportive 15 mm thick and cut to provide full range of motion, maximizing comfort when using the pack without a waistbelt. The dual-density 20 mm thick removeable waistbelt is cut to allow high steps through boulder fields and glacial debris, yet effectively distributes the pack load so it is carried on the hips. It is easily removed to clear your waist for access to your harness and gear loops. Other features include side-panel zip for quick access to thermos or mittens, and crampon straps are replaceable. A rope strap can carry several lengths of fixed ropes or two dynamic ropes and side compression straps fit sleeping pads or an alpine tent. Comes with removeable bivy pad. Hydration compatible.

From Backcountry.com:
"Weight matters when you get on a massive alpine route. That's why Black Diamond pulled out all the stops to make the Quantum Backpack ultralight and ready for the mountains. This climbing pack starts off at a low 3lb 8oz weight (55L size). Strip the removable bivy pad, V-Flex suspension, lid, and waist-belt, and the weight drops to a scant 1lb 14oz. Black Diamond used water-resistant VX21 Dimension Polyant fabric to help this pack achieve its ridiculous lightness."
From Oregon Mountain Community:
"The ultimate blend of light weight and load-carrying ability in a technical alpine pack, the Black Diamond Quantum 65L Pack 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.
