  1. Big Kirk

    So glad I found these biker glasses…I need larger glasses for my head! Really good quality, sporty, wind resistant and my son says I look cool!! Two thumbs up!

  2. Beef Knuckles

    I like the versatility! They have a strap and convert into a pair of goggles which I prefer when I wear my helmet.

  3. Sammy Parks

    I’m a runner and have severe dry eyes that water almost constantly when I run outdoors. Simple wrap-around glasses helped but only a little so I needed something that would fit snug to my face all around my eyes.
    These offer nearly perfect wind protection when worn with the elastic strap as goggles. The optics of the lenses are great and ….the frames are not too bad for goggles!
