Nice fit. I like them a lot. I do not like them under my full faced helmet however. My face shield and the glasses are both polarized so it creates a prism effect.

Ordered the Polariized KDs in the regular size as well as the X size to compare on my face. Returned th Xs no problem!

You really need to adjust the frames. They are Too TIGHT! I have to take EVERY pair I buy...which this will be my 3rd pair; to an eye glass place to ask them to bend the shape of them. Just put a little more pride in the work!

Ive been searching for the original KDs for years! Dont know why I didnt think of the internet duh!. Perfect fit, wont fly off your face while riding & these are POLARIZED!

Pretty much what everyone else has said. The square sunglasses are back in style and with my head shape Ive passed on numerous sunglasses in stores. In addition to needing a recreational pair of sunglasses, I needed something for riding. The small frame hugs my small head perfectly without my eyelashes hitting the lenses and no signs of flying off my face, the lenses dont screw with my vision like cheap flea-market sunglasses, and the polarized lenses cut out a lot of glare and provide great protection. Lastly, the fact they were made with motorcycling in mind was the nail in the coffin -- the option of clear lenses for night riding was a huge plus. I wear these every chance I get and have not regretted the purchase one bit. Shipping was fast and cheap. They look great and the function is there, too.
