SISU Max Mouthguard - 50% Stronger, Maximum Protection for Rugby, MMA, Boxing, Lacrosse, Football, Hockey, High-Impact Sports - Adult Fit, Remoldable Up to 20 Times, Works for Braces

I used this to protect a broken front tooth when I went in for surgery, the anesthesiologist was extremely impressed, he said he'd have refused me as a patient because of the risk of damaging the tooth further. Thank you, my surgery was a success!

One of the best fitting and low profile mouthguards I have ever bought. It was surprisingly easy to heat and mold to my teeth/mouth the first time. Awesome design that stays in place really well (you get that satisfying click into place).

So I’m on number 2 of these mouth guards. Love the face I can still talk with out mouthguard mouth being super bad, breathability is still amazing, borderline no weight, and due to being able to mold it multiple times I can get it to fit my mouth true to size. Being one of the few mouthguards with a ton of moldability if you mess up a bit makes this a great purchase. It’s high quality, I train in Muay Thai and when we hard spar it’s definitely saved my teeth and jaw before. Now, I had to purchase a second one due to me finally biting through (at the time I thought I did) my original one and not taking as good of care as I should of it began to have a bit of a smell to it. Now after I remolded my OG one (and did not bite through it like I thought), cleaning it and remolding it I have 2 of em. The insurance on them is also great. Note - follow all instructions to the letter or watch a video on how to do it. You get 20 times to mold it before it loses its insurance policy and gets weak. It took me 8 times on the first one and only 3 times on this one. This is also great if you have a gag reflex on other guards that aren’t custom ones.

Really firms up stronger than any normal rubbery ones I've ever used. Folded a little weird on my teeth on the outside, which I was suspicious would happen as it starts out flat in the package. But it's so thin it hasn't been noticeable at all when I'm wearing it! The fit remains tight and it just doesn't seem to get smushed or misshapen at all by being tossed in my gym bag pocket with the toiletries for most of the week. As advertised, the "ventilation" is great for drinking between rounds and doesn't even interfere with taking too bad. I'm sold and will buy another spare and again when it's time.

I've bought it because a lot of people on YouTube saying that this one is the best mouthguard. And they were right, it fits incredibly great and it makes easier to breathe, talk and drink, and feels like protect really well. So I 100% recommend it, if you are a hobbyist bjj practitioner - this one worth its money. p.s. I re-boiled it 4 or 5 times until it fit really great - and recommend doing it until it fits great, because it is hard to make it fit well from the first time :)

The product will change shape slightly after fitting, which is enough to make it extremely uncomfortable, if not unusable. I'd definitely recommend buying a standard mouth guard instead of trying one of these types.

After training you jitsu for some years now I always had the fear of getting my teeth knocked out during a roll. Well I caught a nasty knee and it lead me to buy a mouth guard. The sisu 2.4 is just amazing. Moldable up to 20x although I don't recommend doing that. Super comfortable thin variety of colors to choose from and best yet is their 1 year warranty with up to 35k of dental work obviously with stipulations but it eases the mind to know and have that insurance. The fit is literally like a custom mouth guard from a dentist. Its easy to talk. breathe, and drink with it in. Not uncomfortable at all either you almost forget you have it in. I've been recommending this mouth guard to all my bjj peeps. I'm fairly convinced that ive found the only brand of mouth guard I will ever buy from now on.

Very easy to breathe out of. Fits and protects well. A little hard to take out due to how well it fits. . Rubs inner lip raw so be wary of that.
