In search for the perfect pair

Let's just say the baby has a mighty tight grip.  And when it comes to sunglasses, that might not be the best thing for them.  Baby got M's glasses in the baby death grip, and they crumbled, and crashed to the ground.  As if the squash of his little hands weren't enough, the pavement was sure to finish them off.  So now we are in the market for a new pair of men's sunglasses.  There are a few brands that we are looking at, but durability is now one of main priorities.  Of course the mens sunglasses can't be too clunky and have to be polarized too!  That is probably the Number One characteristic that look for, once you have polarized glasses, you can never go  back.  So I am searching the web for some mens sunglasses.  If you have any tips (other than to keep them out of baby's hands) or brands that you really like, let me know.  Off I go to find the perfect pair.
