a good product and price

I found the strap firm and supportive without the cup, the one adult size is M or L but for an L is quite snug fitting, which for me is good. Great to wear for work and play.

It worked for Maui Thai

My son said it was comfortable when fighting not as much when sitting down

Comfy as a mofo

Sick fit. Zero damage to the old crown Jewell’s

poor flexibility and comfort

The fit overall is ok if the product will be used for striking sports. Would not recommend for any grappling arts. The guard is very firm and has no flexibility. Found it to be very uncomfortable during Jiujitsu

Thanks a lot to give us your opinion on  100 Jockstrap Groin Protector Men/Junior. Your technical feedback is very useful for us, especially because we have just released a new range of products for BJJ and we would like to expand it very quick. I ll send your feedback to the product manager. Thanks again

Kind regards

Could be tighter

Bought this for my other half who said it fits well. His only criticism is that it would be better if it fit tighter around the waist as it tends to slide down.

How to choose your groin guard

There are 2 types of groin guard: - Classic, rigid model to protect your genitals when doing boxing or martial arts (Muay Thai, kickboxing, full contact karate), - Pro model with flexible side walls and soft gel edges for unrivaled comfort for disciplines that involve being on the floor (MMA, Brazilian jiu jitsu, wrestling, sambo, etc).

Which size should you choose?

The classic model comes in 2 sizes: Junior and adult. Please note: Brief sizes vary depending on the person's size, but the groin protector size remains the same. To know which size to choose, we recommend you pick one based on your size: under 5'5" = kids' size over 5'5" = adult size

Instructions for use

For a better fit, you could wear briefs or tights over your protective gear.

Care advice

Machine wash the briefs. Clean the groin guard with a sponge and soapy water.
