I'm not a mountaineer so don't really need glacier glasses, but these are just too way kewl. Kewler than Oakleys IMHO (and I've been an Oakley guy forever). Side shields help block out light and don't impair peripheral vision as much as I thought they would. Plus the silver ones add a nice styling contrast to the black frame and gold-ish tint lenses. I like having the photochromic lenses for changing light conditions. I think these would be great for just about anything: outdoor adventure, sports, and casual.
Pros: Ultra light, uber comfortable, and stylin'! :-)
Cons: None really
