Great goggles for mountaineering or backcountry skiing as the lens pops out for ventilation. I wish these worked for me, but they're a bit too big and I can't get a good seal. If most adult goggles work for you, I'm sure they'll be fine. Only tried on at home, never used outside. 

Here is a listing I can find for info: sregear.com/products/julbo-…;

These (and the new version) retail for $299.95. Looking for $180. Can ship, would probably be around $10.
