Frequently Asked Questions

What is HI-PC™ polycarbonate and why is it used?

HI-PC™ (High-Impact Polycarbonate) is an engineering-grade thermoplastic that absorbs high-impact energy without shattering. It is the same category of material used in riot shields and protective face shields — chosen for sports protective equipment because it combines extreme rigidity with a degree of flex, distributing impact force across the entire cup surface rather than concentrating it at the point of contact. Standard hard plastic cups use lower-grade polymers that are more brittle under repeated impact.

How does Shell-Shock™ gel work alongside the polycarbonate shell?

The Shell-Shock™ gel lining sits on the interior face of the polycarbonate shell, between the cup and the body. The hard shell provides the primary structural resistance and distributes the impact across the cup surface. The gel layer then absorbs the residual force that passes through, cushioning the body from the secondary pressure wave. Together, the two layers produce more consistent protection than either material alone.

Is this a standalone cup or do I need a separate supporter?

The CX Polygel Groin Cup Protector is the cup only — it is designed to be inserted into a compression short, jockstrap, or dedicated groin protector that holds it in position. It is not a standalone wearable unit. For a complete groin protection setup, pair it with an RDX groin guard (such as the H1 or R1) or a compatible compression short with a cup pocket.

What sports is this cup suitable for?

The CX Polygel cup is suitable for any contact sport requiring groin protection, including boxing, MMA, Muay Thai, taekwondo, karate, kickboxing, wrestling, and other martial arts. The HI-PC™ polycarbonate shell provides sufficient rigidity for full-contact disciplines. Always check with your governing body or competition rules for any specific groin protection requirements before competing.
