The smallest in the lineup, the Wall Hauler 40 is made using extremely durable TPU-coated body fabrics that can withstand the abuse of big wall climbing. The updated carry system is ergonomically designed with S-shaped shoulder straps. Off-set handles, and a roll-top closure make for easy access when the bag is rigged up. The rim of the bag has been redesigned to be more streamlined and reduce snagging when hauling.
