Technical information

New XP S72-427 Standard

Our mouthguard complies with the new XP S72-427 standard that requires the following features:

- Thicker layers of protection to prevent perforation.
- Built-in breathing channel so that you can breathe even when your jaw is closed.
- Meshed upper and lower teeth to lock the jaw more effectively (protection against fractures).
- Covered gums to prevent teeth from loosening.

Dual-material design

The 500 mouthguard is composed of two materials. The first layer allows you to mould with precision, and the second layer absorbs shocks and ensures a ventilated space for better breathing during exercise.
The 500 mouthguard is much less bulky in your mouth, it makes breathing easier during exercise while improving protection.
