All-purpose, spartan rucksacks for mountain use, the top-loading Black Diamond Speed 40 Pack and 30 are perfect choices for all-day missions in the Rockies, Sierras or White Mountains. The Speed 40, designed with a deluxe V-Lite suspension, can be pared down for light-and-fast summit pushes by removing the pack's top pocket and padded hip belt, while the 30 can be stripped to flyweight class thanks to its removable top pocket, hip belt, framesheet and stay. Both the 40 and 30 are built with water-shedding 210d nylon (plus 400d on high-abrasion areas), have dual ice axe attachments, crampon patches, are hydration compatible, and come in multiple torso lengths.
