Available now in three sizes, the Expedition Duffel were originally asked to develop the large size by an expedition outfitter using yak transports in Nepal. WE duffels have now well-and-truly proven themselves under rough handling in harsh environments. Wilderness Equipment claim that 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.
