SISUMax Mouthguard, Charcoal Black - 2.4mm Thin - Custom-Molded Fit - Slim Design - Remoldable Up to 20 Times - for Impact Sports - Non Toxic - Works with Braces

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.

Heard about this product and underestimated it.Able to move and breathe like never before. If molded correctly, won’t come out or move accidentally. Never buying any other mouthguard again.

As a form football and basketball player who uses this product for Jiu Jitsu I can't recommend this enough. It offers surprisingly well protection for a small size (hence I use it for Jiu Jitsu) while having a perfect fit in my mouth. This guard when formatted properly will not come out unless you pull it with your fingers. Its super easy to mold and like the ads say it can be remolded. The only small issue is that I may have bitten down a little too hard, which makes the plastic a bit thinner. Bite down lightly and you should be perfect. Again like the ads you talk, breath, and drink with the guard in just fine. Although $30 is a bit steep it's definitely worth it if you play a contact sport that requires communication.

As my first-ever mouth guard, I was pleasantly surprised by how easy the molding process was. The company provides clear video instructions, and there are plenty of helpful guides online as well. Shaping it to fit my teeth was quick and straightforward.The mouth guard itself is firm and provides excellent protection for the teeth. It’s comfortable to bite on and feels light, which is great during intense boxing training. I had no trouble breathing or focusing while wearing it, and it didn’t interfere with my performance at all.The only downside is that, at first, it puts some pressure on the front upper gums. It took me about 1–2 sessions to get used to it, and even after removing it, I could still feel the pressure for a little while. This might be a normal experience with mouth guards, though. Plus, once you’re sparring and taking punches, you hardly notice it—pain is part of the fun, right?Overall, it’s a solid choice for a first mouth guard. It does its job well and is comfortable after a short adjustment period. Definitely recommend it for beginners!

Never had this much frustration with a mouth guard before.Forming is easy, and can be repeated multiple times to get the right fit. The problem for me was it never fit.The mouth guard molds into a very hard plastic that is extremely uncomfortable when fully formed. It’ll dig into your gums, and could easily bust the inside of your lip if you took a fall.Once the mouth guard is formed it’ll distort and it won’t fit your mouth like it did when you initially formed it.Don’t buy this mouth guard. You’ll be out $30, and frustrated to all hell trying to fit it, just to find out it’s hard as a rock and uncomfortable in your mouth. Couldn’t imagine rolling or wrestling with this thing in.

This is my 3rd sisu mouthguard, I use for roller derby and have been hit in the mouth several times and so far no broken teeth lol. I like that I can talk without it being too bulky

This is by far the best mouthguard I have ever bought. Super easy to mold, just pop a bowl of water in the microwave for a few minutes until hot to touch and then drop them in. Takes a couple of minutes to soften, then mold them to your teeth perfectly, they are comfortable, I can speak clearly(with a lisp) but you can understand me without me drooling all over myself, I can breath perfectly and drink water and they don't move until I take them out, but the best part is they are sooooo thin!! I prefer them over the damage control brand, and honestly and other brand.

I need to wear a mouthguard for jiu jitsu - but I HATE wearing them. I always gag with them. So I saw two that looked similar and very low profile - Sisu Max and Bulletproof. I bought both. It only took me 2 tries to get a great fit with the Sisu Max and it seems very durable. I had a hard time with fitting the Bulletproof - it took me about 10 times to mold it and it came out so so. I do like how the Bulletproof feels - it’s like having nothing in your mouth. But that’s kind of what worries me about it - it doesn’t seem like it offers as much protection as the Sisu. The Sisu Max feels more durable and it’s still fine for me to wear. I am going to use both but the Bulletproof will probably be more of a backup.
