Black Diamond's most technical climbing pack, the Speed Ultra 35 is ultralight and durable. This balance of weight and strength is achieved through an integration of¯Challenge Sailcloth's UltraWeave 200d ¯body fabric combined with their UltraTNT PSA seam tape.¯The Speed Ultras durability is also boosted by the bomber UltraWeave 400d body fabric on the packs reinforced bottom. A top-loader, the pack is also fully strippable with a removable waistbelt, lid and frame-sheet, as well as side compression, crampon and ice-tool straps. Inspired by the technology used in Black Diamond's Solution Harness, they developed a new, low-profile shoulder strap system that is extremely comfortable while remaining low-profile.
