SISU NextGen Aero Large Guard Mouthguard - Charcoal Black

Perfect mouthguard for martial arts

Good product

Best mouth guard ever! My son has always chewed his mouth guard so terribly it needed to be replaced weekly. This mouth guard is not soft so no chewing and it lasts through lax and football season!! It fits perfectly since it is molded to his top teeth and he can talk and drink with it in. We will never buy anything else!

I've spent more time than any non-professional athlete should trying to find a mouth guard that was low profile enough that I could speak freely and drink from my water bottle. I finally found that product. Priced extremely reasonably, it is the closest you'll get to a customized mouth guard fit without have a dentist take impression molds. I love the ability to re-mold as well. I used it for one ice hockey game, and decided to tweak the fit, and re-fit it. Now it is perfect. At this cost, I'll probably pick up a second one to match my other teams jersey because, well, I'm that guy.

I have to admit, I was a bit sceptical (both of the good reviews and the mouthguard). I play hockey and wanted a mouth guard. I tried a few of the others (including a $50 shock doctor one) and had to throw it away as I just couldn't stop gagging. I tried the SISU one purely by chance as it was at my local hockey store. Fitted it the first time and it was a very close fit, but the molar area wasn't fitted right. Reheated, and amazed it just flattened out. Refitted and it's perfect. A little lisp, but no gagging whatsoever.

Fitting it, even with the instructional video and advice from friends, was not perfect the first time. The process is easy, but I ended up with a weird fold that poked my lip. The cool thing is you can redo it without losing the integrity of the material. I got a perfect fit after a couple trial and error attempts. I can breath easily and talk without taking it out.

So far this mouth guard has lived up to my expectations. I have used it 5 times and the last time I used it for 2 hours for bjj. Even through warm ups and drilling I left it in to see how bothersome it would be. Not at all. Talk, breath and drink easy with this. I might have even molded it a little to tight for my teeth and sometimes have trouble taking it out. But that is an easy fix since it can be remolded up to 20 times. So far I'm happy and I highly recommend.

Good quality, BUT the description fails to mention that the Adult size is for people TALLER than 6 feet (1.8288 meters). Since most of us are shorter than that and needed a medium size to wear, not the larger adult rated size. Problematic...won't order again unless they begin stocking the smaller sizes.

Wonderful. Easy to breathe. Thin. I use for sports AND sleep as a bite guard.

could not get it fitted. it tightens up too much after it cools down.
