Groinguard Shock Doctor Bio Flex SD213
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.

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
