Review on 🦷 Custom Fit Sports Mouth Guard by SISU, Max 2.4mm - Ideal Stocking Stuffer for Football, Hockey, Lacrosse, Boxing - Youth and Adult Sizes Available by Ahmed Rowe

This is the first Kappa I own or have ever used. I picked up the next generation after searching Revain for BJJ mouthguard recommendations. It's a bit more expensive than the other parts, but so far I'm satisfied. It straightens up, you soak it in hot water for a minute, and then fold it over your teeth. It took me a few tries to get the molding right and then a few minor adjustments to get rid of the sharp burrs. Every time you drop it in the water, it magically returns to its original shape, or you can dip a specific part to change the shape a bit. Brilliant! I can drink Nalgen very well with my mouth wide open, can breathe easily, and can more or less communicate with exercise partners, although it's not ideal for that. I happily recommend it as protection for BJJ. J hasn't been hit hard yet, but I hope that bad boy will have my back when I do.
