Crews ForceFlex Safety Glasses with Black Frame and Gray LensCamp CounselorJune 17, 2011I work at a camp in the summer, so I bought these thinking their cheaper cost and flexibility would be appropriate. The flexibility was great for those situations during sports or when the kids got a hold of them, so in that aspect they were golden, however I must say they would fit those with a larger head best. I have an average sized head, I suppose, and they seemed to fit a little wide on me. It would have been nice if they were just a bit smaller. Other than that, they were great shades for their price. I would definitely suggest them to others looking for a nice style and awesome flexibility/durability.
