Specifications
Suitable for
- Boxing
- MMA
RDX lists this boil-and-bite guard for MMA as well as boxing, and sells it in several colours. IMMAF's amateur rules and the ABC's professional rules require a mouthguard in competition. UWW's amateur rules and IMMAF's 2026 rules summary don't allow a red one, so choose another colour if you compete.
- Kickboxing
- Sparring
- Competition
For kickboxing sparring and bouts. RDX makes this boil-and-bite guard in Adult and Kids sizes, with gel padding zones. WAKO requires a mouthguard in every fighting discipline and age category (WAKO Rules 2022, Art. 2.3.1.3). Mouthguards do not need a WAKO label.
- Karate
For karate: a boil-and-bite guard you mould to your own teeth, which RDX sells in Adult and Kids sizes. In WKF kumite (competition sparring), a gum shield is compulsory (WKF Kumite Competition Rules 2026, Art. 2.2.7(b)). The rule lists it without the approval requirement it gives mitts, pads and protectors, and WKF's approved list has no gum shield category. But WKF's rules also say all protective equipment must be approved by WKF (Art. 2.2.10), so ask the event organiser what it accepts.
- Kung Fu (Sanda)
- Competition
For Sanda bouts. RDX describes a boil-and-bite guard with gel padding zones. A gum shield is compulsory in BCCMA Light Sanda (Light Sanda rules 2024, Rule 11). In IWUF Sanda, competitors provide their own gum guard (IWUF Sanda rules 2024, Art. 7.3).
Our verdict
A boil-and-bite mouthguard with gel zones that RDX names for impact absorption, in adult and kids' sizes.
RDX's UK site describes a boil-and-bite guard with a BPA- and latex-free dual-layered shell and named "Shell Shock" and "Molar Tech" gel padding. It has a low-profile design with airflow channels, and comes with a ventilated carrying case, in Adult and Kids sizes and 7 colours.
Boxers who want a straightforward boil-and-bite mouthguard with gel padding zones, in adult or kids' sizes.
You need to know before buying that it covers both arches, or that it works with braces: RDX states neither for this model.
Pros
- A boil-and-bite fit with gel zones RDX names for impact absorption (Shell Shock gel, Molar Tech gel)
- Adult and Kids sizes, in 7 colours
Cons
- RDX doesn't say whether it covers one arch or both
- No statement either way on whether it works with braces
- RDX's claims of WAKO approval and FDA/PAH certification are its own, and we haven't verified them independently
Why we rated it this way
Protection (3): RDX names two gel padding zones, Shell Shock and Molar Tech, in a dual-layered boil-and-bite guard: the normal level for a boxing mouthguard. It doesn't state whether the guard covers one arch or both.
Comfort (3): RDX describes a low-profile design with airflow channels, which is the normal standard for a boil-and-bite guard.
Materials & Construction (3): RDX states a BPA- and latex-free, dual-layer material with "Shell Shock" and "Molar Tech" gel zones. The BPA- and latex-free material goes beyond the normal mouthguard build; the rest is standard.
Value (3): A mid-range price for a dual-layer boil-and-bite mouthguard with gel zones and a ventilated carrying case, which is what mouthguards at this price normally offer.
