SISUMax 2.4mm Sports Mouth Guard for Football, Hockey, Lacrosse, Boxing, Custom Fit for Youth/Adults

I love being able to remold for a perfect fit. It took me a few tries to get it. If you have a friend to help you line it up, use them! For me the back teeth were the hardest. If you have a thermometer, check how hot your hot tap water gets. I found that mine got to 150 degrees so I didn't have to worry about accidentally boiling the guard. Instructions are easy to follow. If you do have to remold it, it actually reverts to it's original form. Even the bite marks revert so you don't have to worry about thin spots. Unlike most other guards I didn't have issues with temperature/sensitivity. Most guards require boiling water (212 degrees) SISU only needs 140-160 degrees or molding which meant not only could I handle the mouth guard but it wasn't painful AT ALL during fitting.It fits a little tight at first but stays in place. I may get used to it or I may have to remold and not create as much suction. Time will tell but I'm not worried. I use it for Kenpo Karate. I didn't have any issues with it during sparring. I had my partner intentionally hit me (lightly) in the face to check the fit. It didn't rub, or have any clicking in my back teeth, I was able to breathe easily, and never worried about it falling out. Drinking with the guard was strange at first but I got used to it fast. I wish I could say the same for talking with it in place haha.I'll update this if anything changes.

Best mouth piece in the game

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 :)

Very slim great design. Have not boxed with it yet but plan to. Down side is it does not. Come with a case. Also, this takes a few times to get it right. Best bet is to only heat the area you need to get right. I suggest getting the front right first them doing the back teeth on a second heat up. Do not suck too tight or the guard will be really hard to remove and put in.

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.

Fantastic mouthguard

This is a waste of money.I was super excited to get this and really p!$$ed I can't get my money back. For $32+ for ONE mouthguard ($29 + tax), they should be able to guarantee something.I watched the fitting video several times before and during the molding process. It never fit correctly. I don't know what i'm going to do with this flat piece of junk. It continuously ribbed in the front, which would have been painful with any headshot in my krav maga classes. No matter what i did, i could not get piece to lay flat. After 45 min and about 8 tries, i gave up. I can't use something that would most definitely cause additional pain. What a piece of junk.Don't waste your money on this and go with traditional. it works. This doesn't.SISU, if you're reading this, do better.

This is the first mouthguard of any kind that I’ve owned or used. I picked up the next gen after bouncing around Amazon, looking for recommendations on mouthguards for BJJ. This is a little more expensive than other pieces, but so far I’m in love. It comes flat, you drop it in hot water for a minute, and then fold it up over your teeth.It took me a few tries to get the molding just right, and then a few more minor alterations to get rid of sharp ridges. Every time you drop it in the water, it magically flattens out back to its original shape, or you can dip a specific part in to remold just a bit. Awesome!I can drink out of a wide mouth nalgene just fine, can breathe with ease and can more or less communicate with training partners, although it’s not perfect for that.Happy to recommend this as a guard for BJJ. J haven’t taken any large impacts yet, but I’m hopeful that when I do, this bad boy has me covered.
