This reduced size mouthguard from Brain Pad is perfect for smaller adults or junior competitors. The Dual Thermoplastic design covers the upper and lower teeth while securing and stabilizing the lower jaw. The built-in TMJ/Brain Safety Space helps cushion impact. The front gap encourages free breathing, even when clinched. This design is particularly popular among Karate Joe's students with braces. This guard comes with an anti-microbial hard storage case.
