Love it!!

Great quality, great fit and much more comfortable in mouth than other types

Amazing mouthguards! I often forget I'm wearing it!! SISU customer service as well. Couldn't be happier!

I love this mouth guard so much. My old one used to be extremely thick and not stay attaches to my teeth. I’d be constantly chewing on it, and it would be really hard to breathe with it in. This one is so comfortable. Attached perfectly. Quick and easy to mould and remould. I can finally breathe. Plus I love my chosen colour (hot sexy pink) highly recommended.

Website was very informative and easy to navigate. Easy to find what I was looking for. I will order from SISU again.

I don't know if I'm an idiot, but I had a really hard time fitting it properly. It always solidified too tight to take off comfortably. but luckily, they are able to be remade over and over. it is really sturdy mouth guard and can take a good hit and still make me feel protected. would recommend to literally anyone who needs a mouth guard. Its so lightweight and easy to talk with it in so people across the field can hear me instead of a mumbled mess trying to hear me through the $1 Walmart mouth guard I had previously.

Good product

Picked up one of these bad boys after taking a knee to the jaw on a botched takedown and feeling the dreaded grit of ground teeth. Easy fitting (and refitting) process, snug and comfortable. Able to talk, drink, and breathe easily. Excellent product.

I seriously love my sis mouthguard. it makes me feel confident and like smiling big while a do a sport that I love (roller derby). I really enjoy wearing it. I would love to have a spare one, and it would be fun to have a sparkly one or printed with fangs! A great product, I would buy it for anyone I care about.

Great mouthpiece easy to form specially because you don't have to boil water either

The regular mouth guards were too thick and bulky for my daughter. She was actually gaging on the field from her old one. The SiSU mouthguard is such an improvement! Its slim design has eliminated the gaging, she can also speak clearly so no need to take the mouthguard in and out to speak to her teammates. Thanks for creating a great product! We will definitely be ordering more!

These mouth guards are the best we’ve had. So easy to wear. Delivery was fast and efficient. Excellent service. Thank you

My mouth guard only fits directly after remolding and only if I leave it in. For the hassle you might as well buy a $5 cheap hunk and cut it to size.

The mouth guard works wonderfully and it isn’t large/bulky or distracting. It was super easy to mold and it is extremely durable. The way it fits paired with the size makes communication a breeze. I love this product, this is the only Mouthguards I ever want to use again!

Grandson said it is the best thing ever. I would buy another one immediately!!

My son has used SISU for for years Won’t Fight without it 11yrs old If you ever need to sponsor a Jiu-Jitsu fighter, lets talk He is always showing the SISU smile on the Podium

Best mouthguard for Jiu-Jitsu

A great product, and it's awesome when the kids learn to re-form their own for the best fit. Especially important for braces/Invisalign users.

I've been using the SISU night guards for years. So much more comfortable than what I could find at the drug store or from my dentist! I just tried the youth size- and like that even better! Keep the innovations coming, Sassa!
