This bag is an absolute machine. I have used it on major trekking and climbing expeditions in Nepal as well in on Mount Kilimanjaro, and it performed amazingly. It comes with a clever little shoe compartment that doubles well for storing dirty clothes, and is also water resistant. The best part is that it is a lot more affordable than the big name brands like The North Face and Helly Hansen.
