Yeah, all those idiots hauling down bags up Everest for the last 60+ years... if they'd only had a Wiggy's.
Everest is cold, which equals DRY during climbing season. Precipitation up high is snow, which means it is not soaking into things. I don't know for sure but I'll bet Everest climbers would fear rain at high elevation almost as much as high wind. IME cold is easier to manage than wet.
