SISU Aero Medium Mouthguard, Noble Navy - 1.6mm Thin - Custom-Molded Fit - Slim Design - Remoldable Up to 20 Times - for Team Sports - Non Toxic

Admittedly, I don’t use this for sports. I have a horrible case of bruxism (sleep grinding) and bought this to help me because most products OTC are so thick they trigger my gag reflex. Because of the slim size and unique material of this mouthguard, it has been helping me finally get a night of sleep. I have chewed it up a bit, but it still works. I cut the excess off the corners and stuck it to the pressure points on my mouthguard to reinforce it. You guys should really consider making a product for bruxism. This is different than most other things. Thanks!

I don’t know how anyone gave this thing a positive review, it’s quite possibly the dumbest and poorest designed product I’ve ever seen. Does not mold to mouth correctly. There is not enough material to mold it effectively and there is not enough material to enable this to provide any reasonable protection whether playing sports or using as a bite guard while sleeping. You might as well shape a large wad of gum into a mouth guard shape...you’d get the same result, and prob more comfortable. This is garbage and shouldn’t be allowed to be sold.

My daughters are in love with this mouthguard. Both play lacrosse and they say they will never go back to the traditional mouthguards. These mold tightly to your teeth almost like the invisalign braces do you literally need to "pop" it out with your fingers so they can open their mouths and talk or yell during a game without fear of the mouth guard falling out. It also a whole lot easier to breath since they don't have to keep their teeth clinched to hold it in while running.You do need to watch the videos to learn how to mold it but they are clear and straight forward. It took us 2-3 tries the first time to get the hang of it but you can remold it over and over if you don't get it right the first time. My older daughter has braces and they recommend letting the orthodontist mold it but she didn't have an appointment coming up so we lined her top teeth with tin foil and molded them over that it and it worked fine - again took a few tries and adjustments to get the final fit.Plan on molding it when you have plenty of time to work with it - it's not something to try for the first time 5 minutes before you need to leave for a game.

I would have loved to loved this product. My 13yr old daughter has used a heavier mouth guard for a while and has not been happy with it. This seemed lightweight and allowed breathability. However, the process of molding it to her teeth was arduous to say the least. After 45 minutes of constantly having to take it out and start over became too much. since you can't return a mouth guard it ended up in the trash (along with my money).I would say her mouth is average size for her age, however each time it either folded on itsself, missed teeth, didn't cover gums, etc and we had to start over. I think the premise is great, however the product falls flat...or crumpled and folded in this case.

I don’t even know where to start with this one. Maybe just don’t buy it?We have owned a lot of mouthguards with 2 sporty kids and this - by far - was the worst of the bunch. It pinched my son’s cheeks in that it would catch (yet it was super easy to mold). He also felt like there was zero protection provided. It didn’t really “lock in” and he didn’t feel like he could bite or clamp down quite right. Convenient- yes. Protective - didn’t seem like it. Comfortable - definitely not.

As most reviews have stated once molded correctly this mouthpiece has an almost retainer like fit. You can talk, drink, and spar freely without ever having to take out the mouthpiece. I used this for BJJ training and really liked the fact I would breath freely without obstruction. However, my issues with the mouthpiece and the reason I don't give it 5 stars is:1) There is a slight learning curve to getting the mouth piece molded properly. This isn't a simple boil and bite sort of mouth piece. The instructions are pretty good but it's still easy to make mistake. Thankfully, the material is very forgiving and allows you to re-boil and start over till you get it right up to a certain point.2) The best benefits of this mouth piece are also part of it's weakness. The mouth piece is very thin and lightweight and I don't know if I would be comfortable taking a hard strike to mouth. BJJ training is one thing but wearing this while striking would be another story.I went with Damage Control mouth guards as my daily go to and haven't looked back.

I play rugby was constantly gagging on a mouth guard I bought at a sporting good store so I tried this one and it's amazing. It did take several times of reheating to get it to fit right however, I wore it an entire match and didn't notice it, could talk, drink, with no problem. Glad I switched.

Excellent product. Works exactly as advertised. My kid can breath easier, drink and speak clearly. But even better is that it took us 4 attempts to mold it correctly and each time we put it back into the hot water, it unfolded and looked new. One time he even bit through the material, causing holes and I figured I'd have to buy another one. But, after placing back in the water, it flattened out again and the holes even sealed up. Remarkable product. And let me add that my kid turned 12 last month and we got the adult size. Nice fit.

I purchased this for BJJ and it's awesome. You can speak, drink, breathe & choke someone out normally when it's in :)When it first arrived I wasn't sure what to make of it and my first attempt to mould it to my mouth wasn't successful. This was my fault as I didn't follow the instructions properly.1. Watch the video on YouTube how to fit the guard.2. Make sure the water you place it in as hot enough so it's like in the video ( mine wasn't first time).3. Make sure you fit it in an area with sufficient light so you can orient the markings on the guard with your teeth. Dont underestimate the importance of this as once I did this correctly the mouth guard was a perfect fit and completly different shape.If you have the budget and like your teeth buy it.

If you're thinking about playing sports, this mouthguard is the best investment, especially when you need to communicate to your team during the game. I play lacrosse and have tried cheaper, and basic mouthguards and found it so hard to control my breathing and talk to my team mates during matches. I tried other cheaper alternatives which added up to be more expensive than this product in the end, and found that non of it worked out well for me. I decided to invest in this product (as a uni student with a budget it was a hard choice!) and have no regrets at all. I can easily close my mouth, control my breathing, and talk clearly to my team. Moulding it was no issue, at first it was daunting as i had read reviews of it going wrong or not working for some, but I took my time and if it didn't feel right, I would just start over.

The jump in the ability to drink, speak, and straight-up breathe sets this mouthguard apart from literally any other one I've ever worn or will wear. INCREDIBLE. It's so lightweight, you don't even feel like you are wearing one and can stay in your mouth for hours without a hitch. I play field hockey so being able to communicate with my teammates all game is crucial and something that previous combat sports-style guards could never offer. Despite arguably offering less protection than those, this is also comfortable and stylish - you don't look like you're an orc showing your teeth in the match photos. For that alone, this gets five stars. The future of mouthguards.

I bought the SISU mouth guard as my daughter wouldn't wear the other gum shields when playing hockey. She complained about the fit and them being uncomfortable to wear, and she would conveniently leave it in her bag or forget to put it in.Since getting the SISU she has been really happy even wearing it for training, and she told me that 2 of her team mates were now getting them. So I guess she has been recommending it to her friends too.

I bought this for my 9 year old daughter for hockey, after having tried a couple of other home-fit mouth guards that were making her gag. After reading the reviews, i went for the adult one and I’m glad I did because it really does shrink. It comes as a thin boomerang shape disk which softens in hot water so you can mould it to the teeth. The front is really easy to mould, but the back stayed kind of flat which has helped with the gagging as the other makes are very thick at the back. It fits very well and stays put whereas the regular type of mouth guards fall away when the mouth is open. They’ve definitely got it right with this mouth guard, I’m so pleased I bought it.
