D3O smart foam - intelligent impact absorption

D3O is an advanced foam material that is soft and flexible during normal movement but instantly hardens upon impact to absorb the force. It intelligently adapts to the intensity of every strike—light impact, light response; hard impact, maximum protection. Specially designed for athletes who demand the best performance-oriented equipment.

Specific features

+ D3O technology - intelligent impact absorption

Equipped with D3O foam technology that intelligently adapts to the intensity of every strike - maximum impact absorption precisely when you need it most.
+ Velcro closure

The hook-and-loop closure is the most widely used closure in martial arts - and for good reason. It is quick to put on, easy to adjust, and provides a secure, reliable fit without anyone else's help.
The closure keeps the wrist stable during training and sparren, and remains just as effective after many sessions as it was on day one. Suitable for beginners and advanced practitioners who value convenience without compromising on support.
+ Lightweight

A lightweight construction means less fatigue during training - without compromising protection or durability. Less weight on the hands or head allows for faster movements, less muscle fatigue, and better technique over longer sessions.
Especially for boxers and kickboxers working on speed and endurance, weight is a factor that matters. Lightweight equipment lets you train harder and longer without the gear holding you back.

Rival - Designed in Canada

In 2003, Russ Anber Rival Boxing Gear founded it - not as a businessman, but as someone who had spent decades in the gym and knew exactly what was lacking in the available equipment. He began innovating, patenting, and building, permanently changing the boxing world with patented designs in gloves, punching mitts, and handwraps.

“My gift was the ability to coach, break things down, analyze and make people understand how things work.” — Russ Anber

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.

What does Intelli-Shock D3O™ mean?

IntelliShock is Rival’s name for gear that uses D3O to absorb impact. You’ll find this technology in selected bag gloves, punching mitts and headgear. Then choose the model that suits your needs: the closure, shape and additional padding vary by product.
