Yeah well I haven't climbed Mt. Everest either. Maybe drinking urine toughens the body in unknown ways!

The fit of the stove to the steel cup didn't impress me either but because the bag is sized to fit the kit, it holds everything together well enough.

You're right the bag is bigger than it needs to be. I would love for them to offer a form fitting option like a neoprene sleeve to hold everything together (it would also help keep the water from freezing)...or something at least less 'paracool'.
