Why climbers love it

The Beta Light 45 is the Viking longship of backpacks: light, swift, yet tough enough to handle anything mother nature throws at it. The sailcloth body shrugs off rain and abrasion, while the roll-top closure locks your gear in tight. The running-vest-style straps fit snug across the chest and shoulders, distributing load without bulky padding. Remove what you don’t need—hip belt, frame stays—and shed weight instantly. It carries your rope, rack, food, and water with ease, keeping essentials within arm’s reach.

For anyone hunting remote lines, chasing dawn missions, or simply wanting gear that moves as well as you do, the Beta Light 45 delivers legendary performance in a sleek, durable package.

Skål to fast moves, light loads, and epic climbs!
