Duffel, backpack, stuff sacks: what bags do I need on Aconcagua, and which one goes on the mule?
What bags do I need for Aconcagua?
A tough duffel of 90 to 120 litres for the mules, which carry it to base camp, and a backpack of 70 litres or more for everything above base camp, where you carry your own loads on the cache-and-carry days. Pack the backpack inside or beside the duffel: strapped to a mule, it gets torn on the rocky trails.
