⚡ At a Glance
  • Wearing Comfort: Curved food-grade EVA conforms to the oral cavity for a soft, snug fit during activity
  • Best for: Youth playing contact sports such as rugby, boxing, martial arts and hockey
  • Not ideal for: Adults needing a bespoke dental appliance or full-arch professional mouthguard

Made from food-grade EVA with a curved design for comfort. Dual-density frame technology adds cushioning to protect teeth and jaws.


Reliable impact protection – Thanks to dual-density frame

Dual-density frame technology uses a firmer outer layer combined with a softer inner core to absorb and disperse impact energy on contact. The layered construction reduces peak forces transmitted to teeth and surrounding tissues.

Effective cushioning lowers the risk of dental damage and lip or gum injuries during tackles and strikes. Suitable for regular training and sparring where repeated impacts occur.

Comfortable fit – With curved food-grade EVA material

Curved design mirrors the oral cavity so the mouthguard sits close to teeth and gums, while food-grade EVA supplies flexibility and resistance to deformation. The material remains soft once moulded, reducing pressure points.

Snug fit stays in place during fast movements, reducing gagging and the need for frequent adjustments. Comfortable wear encourages consistent use for training and matches.

Simple customisation – Thanks to boil-and-bite moulding with included case

Warm water at around 80 degrees softens the EVA for 50–60 seconds, allowing the user to bite and shape the guard for 40 seconds, then cool in cold water for 10 seconds to set the fit. A sterile storage case keeps the guard clean between sessions.

Parents can create a personalised fit at home in minutes without specialist tools, then store the guard hygienically in the supplied case. Quick remoulding is possible if the initial fit needs adjustment.
