SISU Mouthguard 1.6 Aero NextGen

SISU is the mouthguard that is strong, comfortable, remoldable and the one that gives you freedom to drink and communicate while wearing it.
While the SISU mouthguards are less bulky than its competitors, it offers more protection due to its impact diffusing technology. As it is thinner, it is also more comfortable to wear. I, for one, drove all the way home wearing mine because I forgot I still had it in.
The SISU mouthguards are moldable, not just once, but many times. So if you want to readjust your mouthguard to fit more comfortably, you can do so in a blink. Drop it in hot water, let it become soft and pliable and remold!

SISU Mouthguards are the perfect solution for roller derby, hockey, lacrosse, basketball, quidditch, rugby, ...

Fitting your SISU Mouthguard

What you will need:

  • Bowl
  • Hot - but not boiling - water (60° Celcius)
  • Fork or similar utensil
  • Mirror

SISU is simple to fit to a perfect shape around your teeth. It is a quick and easy procedure:

Step 1 
Wash your hands and the material with soap and water.


Step 2
Heat water in a smal bowl (hot to the touch, but not boiling). Place the material into hot water until it turns transparent. Then lift it out of the water with a fork or your fingers.


Step 3
Hold the soft material as shown in the picture. DO NOT LET IT FOLD! The material will glue together, making it hard to reshape.

Step 4
Tilt the head back and open the mouth widely. Place the front teeth so they can gently bite down on the solid cross bar. Press the tongue against the palate. Most of the material should be on the outside of the teeth.

Step 5
Use a mirror. Mold it against the front of the teeth with your fingertips and up on the sides to the gum line to create the shield. Make sure it covers the outside of the molars.

Step 6
Close the lips over the mouth guard and gently create a suction until the material has hardened to get a snug fit. If you are not satisfied with the result just slip the mouth guard into the water, let it soften and straighten out... and start all over again.





Cleaning and Storage

Rinse the mouth guard thoroughly in lukewarm tap water and soap, alternatively mouth wash, each time it has been used.
Additionally, the mouth guard can be brushed with a regular toothbrush using regular tooth paste. Carefully rinse and dry before storage. Store your custom fitted mouth guard at room temperature under dry conditions.

Have these in various colours; fit nicely and easy to mould (and re-mould if needed)!
Very good for communicating whilst playing, which is essential! It's my go-to model as mouthguard!

Easy fitting, they also have a fitting guide on YouTube. You can talk, drink and breath easily with the mouthguard in your mouth for an entire practice. It's also fun switching colours once in a while.
