My husband received a pair of Oakleys a few years back at a Homebuilder Show in Orlando and loves them.  They even held up through a baby/toddler playing and bending them.  When I saw these were only $60 or so, I decided to get them for his birthday.  He has a large head and I was worried because he is picky with sunglasses but he loves them and they fit him great.  He used to be one to go through a few pair of $5-10 sunglasses a year but since getting Oakleys he says they are worth it and he don't lose them anymore.

My husband still loves his sunglasses but he said they are not nearly as comfortable of a fit as his other Oakleys but I only paid in the $60s for these whereas to buy an exact replacement for the ones he already has, they would have been around $130.
