The RDX 3W Mouth Guard is a boil-and-bite mouthguard engineered for boxing, MMA, Muay Thai, rugby, and contact sports where dental and jaw protection is essential. A properly fitted mouthguard is one of the most important pieces of protective equipment a fighter can wear — the 3W delivers a custom-like fit without the cost of a dentist-made guard.
Boil & Bite Custom Fit
The thermoplastic material softens in hot water and moulds precisely to the shape of your teeth and gum line when bitten. This creates a snug, personalised fit that stays in place during hard sparring and prevents the guard from shifting mid-round — a common problem with generic one-size guards.
Protection Zones
Multi-layered construction distributes impact across the full jaw, reducing the transfer of force to the teeth, jaw joints, and skull. The 3W is designed to protect against the type of forceful contact common in boxing and MMA sparring, covering both upper teeth and the lower jaw simultaneously.
Breathing & Comfort
The anatomical channel design allows normal breathing during intense rounds without requiring the guard to be removed between exchanges. Comfortable enough to wear for full sparring sessions without jaw fatigue.
Available Options
Available in Kids and Adults sizes across Black, Red, and Blue colourways. Always ensure your governing body approves the mouthguard before competition use.
