The Beta Light 45L is Black Diamond's answer to the ultralight backpacking revolution. Inspired by our athletes and utilizing a running-vest style suspension harness system from their distance running series packs, the Beta Light 45L is simply built for moving fast on overnight adventures in the backcountry. Whether you’re spending months on the PCT or making the most of a two-week trip, the Beta Light 45L carries all the essentials in a waterproof, sleek design that doesn’t sacrifice comfort.

Built for moving fast and covering long distances, the Beta Light UL 45 is the ultimate blend of durability, lightweight construction and load carrying comfort. BD partnered with Challenge Sailcloth to bring their Ultra 200 body fabric to the Beta Light series to create one of the lightest yet most durable packs on the trail. This durable fabric, combined with taped seams and a roll-top closure, make the pack waterproof and able to stand up to day-in-day-out use. A simple, Power Mesh stretch pocket and two side pockets provide plenty of external storage options, while the pack’s running-vest inspired shoulder strap harness system provides support and comfort with additional snack pockets and water bottle storage options. A removable hip belt, lightweight aluminum frame, and removable foam back panel provide options for reducing weight even more.
