The SISU 3D Custom Fit Mouthguard is one of the most comfortable and easy-to-wear mouthguards on the market. At just 2.0mm thin, the 3D Mouthguard's low profile allows for easier talking, drinking, and breathing than when wearing traditional bulky guards. The SISU 3D is non-toxic, works with braces (when fitted by a dentist), and carries a $50,000 limited dental warranty. Two new enhancements include the pre-formed shape that makes fitting even faster and easier, as well as the variable thickness of the inner and outer walls. The inner wall is thinner for comfort and breathability, while the outer wall is thicker for more protection and perforated to make drinking easier without taking your guard out. SISU 3D Mouthguards are remoldable up to 20 times and suitable for all ages 7+.
