Our packs were smaller and lighter than the porters. My whole pack is a dry bag and I typically carried my sleeping bag, dry warm clothes, first aid kit, toiletries, contacts, glasses, snacks, lunches, two or three liters of water or gatorade, a water filter, two cameras, and the gps (about 10 kilos or 22 lbs). My porter carried the tent, thermarest, sandals, dinners, some snacks and lunches, plus kitchen supplies – about 16 kilos or 35 lbs at the beginning and down to about 10 kilos at the end after we’d eaten the food – PLUS his own food, a tarp and change of clothes that weighed another 5 kilos or so at the beginning.
