Shock Doctor Bio Flex SD213 Groinguards

The Groinguard Shock Doctor Bio Flex SD213 is currently one of the best groinguards available for purchase. Kicks are well absorbed by the Shock Doctor cup thanks to the 'BioFlex Cup,' and the ventilated bio-shape provides crucial protection and cooling to the protected areas.

Good fit

The Shock Doctor cup is worn by many well-known fighters from the UFC, Bellator, Glory, and Enfusion. Thanks to the elastic band, the extremely strong cup stays securely in place.

Top-quality removable cup

The cup of the Groinguard Shock Doctor Ultra is made of special hardened plastic. This ensures you the very best possible protection. The cup is available in sizes: S, M, L, XL, and XXL.

Groinguard Shock Doctor Bio Flex SD213

The Bio-Flex Cup is a slightly elastic cup that comfortably flexes during training. The cup is treated to be anti-bacterial. Thanks to the rubber protective layer around the cup, it feels more comfortable than a standard cup and does not feel hard.

The cup of this groinguard is removable, so the "jockstrap" (the shorts) can be washed. This allows you to always keep the product clean and well-maintained.

Groinguard Shock Doctor Bio Flex SD213: the importance of a good cup

In most martial arts and combat sports, a groinguard is desirable. After all, it concerns vital areas where serious injury can occur if they are not protected.

That is why in hard fighting styles and realistic defense systems, such as Krav Maga, training is almost exclusively done with protectors from Shock Doctor.

In almost all combat sports—such as karate, kickboxing, and taekwondo—techniques target the groin. However, accidents can happen easily, and you can always accidentally receive a kick or knee there during a match or training. Therefore, in competitions, a cup for men is almost always mandatory.

Features of the Shock Doctor groinguard:

  • Removable top-quality plastic cup
  • Elastic waistband
  • For youth and adult men
  • Suitable for all martial arts and systems
  • Nice soft finishing on the edges of the cup

Tips for Shock Doctor Groinguards

The Shock Doctor G5 is specially designed for women and protects the groin and lower abdomen. Available in multiple sizes, refer to the size chart on the product page for the right recommendation.

Wipe the groinguard after every training session with a damp cloth and let it air out. Never store it damp in a closed bag.

Frequently Asked Questions — Groinguard Shock Doctor Bio Flex SD213

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.

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.

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.

What is the background of the Shock Doctor brand?

Shock Doctor has grown from the undisputed leader in mouthguard technology into the world's leading innovator in sports protection. Our belief in combining design and technology to achieve better protection and performance is now trusted by fearless athletes across a growing range of products and sports, from youth to amateur to professional.

In addition to mouthguards, Shock Doctor is also at the forefront of protecting crucial and vital areas of the body. They make the best athletic cups and groinguards for men and women. These are used in intense combat sports, such as boxing and kickboxing, as well as in other contact sports, such as ice hockey, field hockey, and rugby!
