50% thinner || 30% stronger || Talk, breathe, drink || Great for airsoft Some players like to wear balaclavas in a vein effort to prevent tooth or flesh wounds to the face. They may help but does not really stop a wound. While we don’t have a fix for the face per se, we do have an answer for the teeth. These SISU mouth guards will protect your teeth and allow you to breath easily and communicate as well. Germs cannot live on them and you can drink without taking them out! For that hard-core Airsoft Milsim player there is just no other option!
