This is the best mouth guard I have bought so far. Compare to others This mouth guard stays in the mouth until you take it out.

Super comfortable! My daughter couldn’t stand mouth guards previously. She now asks if she could wear Sisu instead of her prescribed invisalign during the day.

The thinnest mouthguard I know, yet it still provides quality protection. With the back to school special going on, you can’t go wrong.

Fits so good. First time I’ve used a mouthguard that didn’t make me gag when I got winded. Buying a second already. Game changer.

I reckon I don't have an average mouth, because these always crinkle up and absolutely will not smooth out no matter what I do. I originally got the Max, but I'm waiting on an Aero small and a Go. Hopefully they'll work out better for me.

I have a mouthguard for hockey, my son has one for his lacrosse and I have a SOVA nightguard so I don't grind my teeth at night.

good:)

I’m in 7th grade and this mouthguard is great fo rugby.As a kid I tend to chew my mouth guard a lot I even went threw 3 in one football season but this mouth guard has had no problems so far and is a great protective mouthguard it’s also very breathable.

I recently got this mouthguard for lacrosse and I love it! I have braces and it fits perfectly with them. I took a couple of tries to mold into my mouth, but after that it was perfect!

Absolutely best fitting mouthguard I’ve ever tried.

These mouthguards are very easy to form and fit great.

Really like my mouthpiece, confortable and I can easily drink water.

Much easier to get a great fit.It’s like having nothing in your mouth.Great Product

This is the most comfortable & best fitting I have worn. Easy to mold & fit is perfect, easy to breath, talk & drink water with it in!

I have tried a couple other mouth guards after I had used one of these in the past. Nothing compares to the Sisu mouth guard. These are simply the best ones !

The mouthguard spray from Sisu is wonderful and fresh. Thank you.

Like the added benefit of the "vip" program. Just wish it woulda have saved me the money. Mouthguards are great!

Things went as well as I could have hoped. The products were exactly what I was looking for, and are the highest quality. The navigation of the website was easy and efficient, and I will definitely order again!

It's lightweight and protective, very comfortable. Molding it was a little worrisome because I feared it would fold on itself! Easier than conventional mouthguards in that I didn't have to boil water to make it pliable. Worth it the money, for sure!
