Purchased initially about 7 years ago, eventually the nose pads started to fall off. Submitted the warrantee online, boxed them off and had a new pair within 2 weeks. No hastles, gotta love it...
First sunglasses I could wear in which my eyes did not tear when snowboarding. Then found I loved them for every activity. Never seen a scratch on the lenses .. and they have a lifetime warranty .. even if you break em .. just don't lose em and you'll have these forever. Light weight, comfortable, great lenses, polorized .. indestructable.
