The Mens ONeills Gel Pro 2 Mouth Guard is perfect for training sessions and matches, featuring a gel coating interior for easy moulding to the teeth along with anti slip pads to prevent slipping when the jaw is shut. A central air passage allows air to pass into the mouth when the jaw is shut and an outer shield helps to absorb shocks, impact and pressure. > Mouth guard > Central air passage > Outer shield > Anti slip pads > Gel coated interior > ONeills branding
