CO.R.E. Sports carries the SISU Mouthguard for one reason: It is the best out there! Getting tired of seeing my daughters run around chewing on their mouth piece while playing, I was on a mission to find a custom-fit mouthguard to eliminate the danger of not having the right protection. 

The SISU mouthguard is revolutionizing mouthguards by offering more protection and less mouthguard. Youth or adult, braces or not, for high-impact sports or a pick-up game in the backyard — the SISU guard is the ultimate sports mouthguard.
