Frequently Asked Questions

What is the difference between the CX Polygel Groin Cup and the CX Polygel Groin Cup Protector?

The CX Polygel Groin Cup is the cup insert only — a polycarbonate shell with gel lining designed to be inserted into a compatible supporter or groin protector. The CX Polygel Groin Cup Protector is the full integrated unit that includes the cup within a wearable protector housing. If you already have a supporter or groin protector with a cup pocket, the standalone cup is the right choice.

What does S.P.P™ design mean?

S.P.P™ (Strategically Placed Panels) is RDX's design methodology for positioning structural elements within protective gear to keep it anchored during movement. On the groin cup, the S.P.P™ approach uses the 4-way stretch loop panel to grip the cup pocket in the supporting garment, preventing the cup from shifting laterally or vertically during kicking, grappling, and explosive movements.

Does the polycarbonate cup protect against nerve damage?

The rigid polycarbonate shell distributes the force of a strike across the entire cup surface, preventing the concentrated point-load that can cause nerve compression or damage to the groin area. The Polygel™ gel lining then absorbs the residual force that reaches the body. This combination is designed specifically to address the risk of nerve damage from repeated or heavy impacts in full-contact training.

How do I clean the CX Polygel Groin Cup?

Wipe the polycarbonate shell and gel lining with a damp cloth after each session and allow to air-dry. Do not submerge in water, machine wash, or use abrasive cleaners, as these degrade the gel layer and can weaken the polycarbonate over time. For the loop panel, hand-rinse cold and air-dry. Inspect the cup periodically for cracks in the shell — a cracked polycarbonate cup should be replaced immediately.
