Sisu Aero Mouthguard Features

The mouthguard was designed so that it can absorb impact forces from contact sports like boxing, Brazilian jiu-jitsu, hockey, football, lacrosse, and more. The perforations and crumpled zone allow the force to be better distributed and will not reflect on your teeth or jaw.

Being able to breathe properly is always an advantage when you are playing a fast-paced game. It allows you to perform better than your opponents. Sisu Aero is great when it comes to breathing, talking, and staying hydrated. 

Another important feature is the fact that it is a thin mouthguard. 1.6 mm is enough to offer great protection and to make you forget that you use a mouthguard. 

If you think you don`t know how to mold a mouthguard or have never done it, you can rest assured because this product can revert to its original shape multiple times. 

Sisu Aero Nextgen is also providing a premium dental warranty for kids (11+) and adults.

Pros and Cons of using the Sisu Aero Mouthguard


  • The molding process is very easy and if you do it wrong you can try again. Because the mouthguard is thinner than the standard products available on the market and the materials used, you can remold it multiple times.
  • People that are sensitive and get the gag reflex reported that they can use this mouthguard without any problems compared to other mouthguards. The reason for that could be the thin size.
  • It is very comfortable and you will forget that you even have it. With this mouthguard, you can talk like a normal human being, breathe and drink water from a bottle easily while offering solid protection. Being able to talk is very important in team sports like lacrosse.
  • Available in a wide variety of colors that suit your style (white, black, electric blue, forest green, purple punch) and work with braces.


  • It might be a little tricky to mold it the first time. If it does not fit the first time you can try again.
  • Not suitable for contact sports that might have high force impacts. Sports like MMA are not safe with this mouthguard. You can use Sisu Max for that.

When you receive your Sisu mouthguard you will see something that you don`t expect. The mouthguard is completely flat (boomerang shape). Sisu does this for all of its products.

In the package, you will also receive the instructions. Read them and you will find out how to heat and mold this mouthguard. 

Here things are a little bit different compared to boil and bite mouthguards. For this particular product, you have to be a little bit more delicate. Line up your teeth and the bite pad using mostly your fingers and some suction.

If you want to see the entire process explained by a professional you can watch this video:

Don`t be discouraged if you make a mistake the first time you try. This product can take several molding tries.
