The CHECKMATE is the latest sport frame in the RAZE family. These are made of TR90 for the most durable and almost unbreakable frames. They can be bent, stepped on, or just beat like crazy but still look and feel like new. The high grip nose pads, and rubber sliced through the arms, will keep them from ever moving. With vision this perfect you can stare through these lenses at your competition thinking…CHECK and MATE.
