These are pretty good sunglasses.  They allow for larger heads, but that piece which allows for head adjustment sometimes pinches me.  Also, the sunglasses don't cover as much as I'd like, but it does cover a good portion.  These are well worth the price.  The original reason I bought these was because my previous pair (different brand) broke due to too much sun and salt at the beach.  Unfortunately, I have not been back to the beach since to test this new pair out.  When I get the chance to go back, I'll update this review with my findings.
