I have to say, it's the best TNF pack I've used. It's held up in some surprisingly rugged conditions, but it's still perfect for cragging. TNF Athlete Alex Honnold, Rock Climber, free-soloed Half Dome. Our new, bombproof 55-liter pack is purpose built for climbing big racks and taking serious abuse at the crag. This top-loading pack is constructed to stand up on its own and has a cinched top, so you can access and organize gear quickly. Removable hipbelt and frame sheet.
