The DMM Porter range of bags comes in 45 and 70-litre sizes, featuring a blow-molded back panel made from heavy duty Tarpaulin and a sturdy carry system. These bags are designed to transport heavy loads over longer distances than DMM Transit bags. They are constructed with heavy-duty weather-resistant material and a waterproof lid to protect the contents from the elements. Additionally, they have a moulded back panel and padded rucksack straps to provide a sturdy carry system. The shoulder straps are detachable for snag-free hauling, and large haul/grab loops make for easy clipping and hanging. This range of bags is designed by climbers, for climbers.
