Rival Boxing Gear: Russ Anber, innovations and international growth

Is a groinguard mandatory?

That depends on the sport, type of practice, and competition rules. A groinguard may be recommended or required during training, but there is no universal rule that applies equally to every martial art, every exam, and every participant.

Check the equipment requirements for your training session or event and choose a model designed for that purpose. A proper fit and secure fastening remain important, even when the groinguard is required.

Why are groinguards for boxing so different from regular jockstraps?

A compact cup protects the groin while leaving plenty of room for footwork. A larger boxing groin protector or no-foul protector adds padding around part of the lower abdomen and hips. That makes it a good choice for boxing training and sparren. The Rival RNFL Pro, for example, is quick to adjust with double hook-and-loop fasteners; a lace-up model such as the Rival Guerrero can be laced for a snug fit.

Can groinguards and cups be washed?

Clean the parts separately. Remove a removable cup from the fabric shorts before washing them. Wipe the cup clean after use with a soft, slightly damp cloth and let it dry thoroughly. Clean larger padded no-foul protectors by wiping them down, not by putting them whole in the washing machine. Don’t forget the belts, fastenings and lining.

What size groinguard should I get?

Use the size chart for your model: choose XPRT Basic men's by weight, and Shock Doctor and Rival by waist size. For XPRT Basic men's, size M is 51–70 kg; for Shock Doctor, M is a waist size of 81–86 cm, and for Rival RNFL Pro, 76–86 cm. Women's models have their own size charts. Then lift your knees and twist to check that the protector stays in place without pinching.
