+ Handcrafted with pride

Each product in the RFX Guerrero line is handcrafted from the finest cowhide. Artisanal production guarantees consistent quality and craftsmanship that machine-made gear cannot match—visible in every detail, felt during every training session.

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

The (Short) History of Rival Boxing Gear

Is a groinguard mandatory?

Yes, usually.

A groinguard is often mandatory or recommended. For boxing, kickboxing, and karate training, for example, it is recommended. In krav maga and self-defense systems, it is mandatory. The area protected by the groinguard is, of course, highly vulnerable to injury.

During exams and competitions, a groinguard is always mandatory for both men and women.

Why are groinguards in boxing so different from regular cups?

A "regular" cup only protects the groin. A no-foul protector in boxing protects the kidneys, liver, and groin.

In boxing, the chance of taking punches to the liver or kidneys is much greater than in kickboxing. Extra protection is therefore needed to minimize the risk of injuries and damage.

Can you wash groinguards and cups?

Yes and no.

This depends on the brand and model. You can almost never wash the cup (the hard part), nor do you need to. Most regular groinguards are built into a kind of sports brief (jockstrap). You can remove the cup and wash the brief.

The larger kidney and groinguards (No-Foul) designed for boxing obviously cannot be washed in a washing machine either. This really shouldn’t be necessary. You can simply wipe them down and dry them to keep them fresh.

Naturally, you can’t wash the steel groinguards either. The metal is not designed to withstand this.

What size groinguard should I get?

When choosing the size of groinguards, the main consideration is waist circumference rather than the cup size itself. For each groinguard, we have included a unique size chart (in the size selector and below in the product information) for that specific brand and model.
