Black Diamond Beta Light 45 Backpack

A fast-and-light alpine pack for ski tourers and trail runners who need 45 liters of volume at a weight that doesn't penalize pace on technical terrain, the Black Diamond Beta Light 45 Backpack uses Ultra 200 construction to stay under 2 lbs while adding a roll-top closure and taped seams for high-alpine weather resistance. The running-vest-inspired shoulder harness moves freely during sustained uphill output, and removable hip belt pads let you strip weight on summit approaches where the pack carries only a thin emergency kit. Load capacity tops at 40 lbs, placing the Beta Light 45 at the intersection of ultralight performance and practical alpine volume.
