Black Diamond Beta Light 45 Backpack - Storm Gray

The Beta Light UL 45 offers the ultimate combination of durability, low weight, and comfort, and is designed for fast-paced hikes and long distances. Black Diamond collaborates with Challenge Sailcloth to equip the Beta Light series with Ultra 200 fabric, creating one of the lightest yet most durable backpacks on the trail. This durable material, combined with sealed seams and a roll-top closure, makes the backpack waterproof and resilient for daily use. A simple stretch pocket made of Power Mesh and two side pockets provide plenty of external storage options, while the running vest-inspired shoulder straps and hip belt offer support and comfort along with additional storage for snacks and water bottles. A removable hip belt, a lightweight aluminum frame, and a removable back pad offer options for further weight reduction.
