I'm 30 and this is my first pair of sunglasses that cost over $20, ever...

Wow, SO WORTH IT!  They are so light!  I haven't run with them yet (will do so today), my only concern is that they don't hold on to my head all that tight, hoping they don't try to fall off.  But if I end up needing to revert to my cheap sunglasses for running, thats ok too.

They look great and I've gotten a lot of compliments, I'm hooked!
