I knew when I ordered these Sun glasses from Fat Skeleton that they would do what they are made to do, which is block the sunlight and help give you clear vision, and more. When worn they give your eyes an instant relaxed feeling as unwanted sunlight is blocked out. They sit comfortably and as with other pairs of FS's similar glasses they stay on your face when wearing an open face helmet and do not rub or lift from the ears. All in all they're a great pair of glasses and well priced too. Cheers all at Fat Skeleton.
