Junior Sisu NextGen Mouthguard

Custom-fit Sport Mouthpieces | SISU Mouthguards

The SISU mouthguard: an astonishingly thin, obnoxiously bright, boomerang-shaped hunk of technology — revolutionizing mouthguards across the universe by offering more protection and less mouth guard. 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 mouth guard you once thought too good to be true.

Using revolutionary Diffusix™ technology, SISU Mouthguards are 8 times tougher and 30-50% stronger than conventional mouthguards. You’ll be able to start each game with confidence knowing that no matter how hard you hit, your SISU is there to protect you.

A mouthguard shouldn’t be something you dread having to wear because it’s uncomfortable. In contrast to the large, clunky guards you’ve come to expect, every SISU is a super-slim 1.6 mm thin. They’re so small that you’ll honestly forget you’re even wearing a mouthguard!

SISU provides a comfortable custom fit that allows you to keep your guard in your mouth the entire game or practice. You don’t need to constantly remove your guard to talk, breathe or drink. This means that fewer germs will be transferred from your dirty, sweaty hands to your SISU Guard.

SISU is the mouthguard that allows you to adjust over time, maintaining utmost comfort and protection. Beyond custom fitting, every SISU mouthguard can be remolded to ensure the best fit. Simply place your SISU Guard back in hot water, and it becomes soft and pliable, and ready to remold.
