Black Diamond Speed Ultra 35 Backpack

Engineered for fast, technical alpine climbing, the Black Diamond Speed Ultra 35 Backpack is built to deliver an exceptional balance of ultralight performance and expedition-grade durability. Designed for demanding environments from glaciated peaks to steep alpine routes, this 35L climbing pack uses advanced materials to reduce weight without compromising strength.

At the core of its construction is Challenge Sailcloth UltraWeave™ fabric, combining 200d body material with reinforced 400d panels in high-wear zones. Paired with UltraTNT™ seam tape, this creates a highly durable yet lightweight system suited for repeated abuse in harsh mountain conditions. The pack’s modular design allows you to strip it down for summit pushes or configure it for longer objectives, making it a versatile choice for climbers seeking a lightweight alpine pack, technical climbing backpack, or fast-and-light mountaineering pack.

A low-profile harness system inspired by climbing harness technology ensures a close, stable fit, while upgraded hardware and attachment systems provide reliable performance in cold, snowy environments. Built for efficiency, durability, and speed, the Speed Ultra 35 is purpose-driven for serious alpine missions.
