These super-tough Expedition Duffel Bags use heavy-duty Australian Canvas coupled with detailed design and reinforced construction to absolutely minimise wear and tear. Available now in three sizes, we were originally asked to develop the large size by an expedition outfitter using yak transports in Nepal. (Everything else on the market, tried over many seasons had failed). WE duffels have now well-and-truly proven themselves under rough handling in harsh environments. You will not find equivalent durability or fit-out. The 120L large size was specifically designed long so it comfortably accommodates a 100L pack along with other gear (snow stakes and other climbing hardware, for example). Lockable zips keep out the curious few, while multiple, super-reinforced lashing points and grab handles make handling, hauling and load building with these duffels a breeze.
