Sports glasses need to protect your eyes and also stay on your head no matter how rough and tumble your sport or activity is. These nice shades by X-Loop do both, with a frame that is molded to fit your head and an interior textured grip pattern, they'll stay with you when you dive or get tackled. The lenses are large and set in a semi-rimless fashion, and they flow together in the middle in the shield style. The finish is dark enough to block the sun, but still lets you see.
