PolyShoK™ is a proprietary blend of plastic designed specifically for athletic mouthguards.  It has the unique properties of being able to form to the mouth at low temperatures, softer resulting in greater comfort, and absorbs more destructive force thus transmitting less to the teeth, jaw, and brain.

PolyShoK™ has been A.S.T.M. (American Standards in Testing and Measurements) to be 152% more shock absorbent that leading traditional mouthguard (ethyl vinyl acetate) materials.  These results are reproducible in any A.S.T.M. certified lab in the country.

Below are the results of this independent testing. Force tested at is equal to a hockey puck traveling at a sped of 83 m.p.h.
