The sunglasses look very cool and block a good portion of the wind when biking. They are light weight and do not pinch or leave heavy marks when biking all day. This blue pair actually has a black frame with blue accents and sports clear blue lenses - more like a prism as they tend to change colors when moved from side to side. These provide very light protection as they are not as dark as the other XLOOP glasses.

They do seem to fall apart easily. The nose piece on one of mine came off and the lenses do pop out when cleaning. Seems to be a lack of glue, but I super glued them and now they are holding up throughout the summer.
