The Klim D3O Pro Pads have been constructed from a specialized compound for high impact resistance that has been formed into a thin, flexible pad. Typically other safety pads with this level of protection are thick and heavy, this makes the thin D3O pads (8mm thick), stand out from their competition. Not only are the D3O pads comfortable, and extremely flexible, but they are also completely washable! The Klim D3O pads are high quality performance, shock absorption pads that have been tested to the highest standards.
