Good but slightly too large

Slightly too big. I'm 6ft & would have been better with a medium! Feels nice in & the channels really help with breathing! I fo BJJ and this feel really comfortable in, especially when being caught in a choke.

Un réel protège dents…

Un réel protège dents bi-matière ce n'est pas ça ! Pratiquant de sport de combat depuis de nombreuses années j'ai eu l'occasion d'essais beaucoup de protège dents. C'est certainement le meilleur que Decathlon ai à proposer mais il n'est pas adapté pour les pratiquants réguliers et expérimenté.

New xp s72-427 standard

Our mouthguard complies with the new XP S72-427 standard, which stipulates the following features: - Thicker to prevent perforation. - Built-in breathing channel so that you can breathe even when your jaw is closed. - Meshing of the upper and lower teeth to more effectively hold the jaw in place (protection against fractures). -A gum covering to stop the teeth from coming loose.

Dual material design

The 500 mouthguard features 2 materials. The 1st layer gives you a perfect fit while the 2nd absorbs impacts and lets you continue to breathe easily. The 500 mouthguard has a much more compact design, making breathing easier while increasing your level of protection.

Instructions for use

Always wear your mouthguard during training sessions and competitions. To get the shape right when you mold it, soak it in boiling water for exactly the right amount of time. This time will be indicated in the instructions and may vary from model to model. Watch the video tutorial to find out how to mold your mouthguard.

Care instructions

Wash in fresh water. Leave to dry naturally before putting it back in its storage box (original box). For optimal protection, replace your mouthguard at least once per year or as soon as it starts to show signs of wear.
