Our purpose-built commuting duffel sized at 30 liters, the Black Diamond StoneHauler 30L Pro comes with a feature set engineered for daily travel or overnight adventures. You can strap this duffel on in the morning with the adjustable (and removable) backpack straps, bike to the gym for a pre-work sesh, and then stuff your chalky climbing clothes into the integrated DirtBag storage system. The fully padded, exterior-accessed laptop sleeve keeps your machine safe while on the go, as well as the side-to-side padded body construction which consists of 5mm closed cell foam for puncture and fabric abrasion resistance. Two interior zipper pockets and one exterior zipper pocket allows you to keep smaller items organized, and the mono-mesh ID pocket let's everyone know it's yours. Also wrapping the entire exterior of each duffel is our Haul-loop carry system; a continuous, tubular webbing loop tested to 2kN by the same machines that load test our carabiners and Camalots.
