What is the advantage of a double-layered closed-cell foam with a hard shell cup?

Closed-cell foam does not compress to zero — unlike open-cell foam that can be fully flattened on hard impact, closed-cell foam maintains a minimum thickness even under the highest load. Combined with the hard polymer shell, this provides a rigid outer barrier that spreads the initial impact across the whole cup surface, while the foam layers absorb the residual force before it reaches the body. The dual-layer approach is more protective than a shell-only or foam-only design.

Can I insert an additional cup for extra protection?

Yes — the R1's cup area is designed with ample space to accommodate a second cup, such as the RDX CX Polygel Groin Cup, for layered protection. This is particularly popular for heavy sparring and competition, where the primary cup handles initial impact while the secondary cup provides a further buffer. If adding a second cup, ensure the combined fit does not restrict natural movement.

How do the lace and elastic strap adjustments work together?

The elastic strap provides the primary fastening — an elasticated waistband that accommodates a range of waist sizes. The lace adjustment allows fine-tuning of the cup position, securing the cup against the body so it does not shift during movement. The two-system approach means the guard stays in place during explosive and ground-based movements where a single elastic band would allow the cup to migrate out of position.

What is the R1 CE certified for?

The R1 is CE certified by SATRA Technology, a recognised international testing and certification body for protective sports equipment. This certification confirms the guard meets minimum protection standards for boxing, MMA, and martial arts use. Always check with your governing body for any additional certification or specification requirements if you intend to use the guard in sanctioned competition.
