Designed for fast progress and long distances, the Beta Light UL 45 offers the ultimate combination of durability, lightweight design, and carrying comfort. We collaborate with Challenge Sailcloth to equip the Beta Light series with Ultra 200 fabric, creating one of the lightest yet most robust 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 ample external storage options, while the running vest-inspired shoulder straps and hip belt offer additional storage for snacks and water bottles, alongside support and comfort. With the removable hip belt, lightweight aluminum frame, and removable foam pad, the weight can be further reduced.
