Duffel Stonehauler 90 L. Black Diamond Stonehauler 90L is the perfect duffel you want for quick missions.. The expedition duffel that checks in at 90 liters, the StoneHauler 90L is engineered to organize, store, and haul your climbing and skiing gear to the greater ranges. The duffel features the touchstone travel-bag innovations, like the Haul-loop carry system; a continuous, bomber tubular webbing loop that wraps the entire duffel and is tested to 2kN by the same machines that load test the carabiners and Camalots. This provides a secure clip-in and carries a solution to keep you confident that your gear is secure if it's strapped to a truck or a pack mule. The DirtBag storage system gives you an integrated way to stow your laundry, and cinches closed with an alpine skirt closure. The 90L features the side-to-side padded body construction as well, which is unique to the StoneHauler duffels and consists of 5mm closed cell foam for puncture and fabric abrasion resistance while carrying gear such as quickdraws, trekking poles, or a rack of cams.
