Groin Protector FAQ

Is a groin protector necessary?

Though it’s not compulsory as such, a groin protector is certainly one of the most highly recommended pieces of kits!

Inevitably when participating in any form of close contact sport, the potential for receiving a blow to the groin or abdomen is extremely high.

Yet, alongside the indescribable pain, the potential damage several blows can do to this area isn’t worth thinking about.

Therefore, to eliminate this, a groin protector can be bought and used with a minimal amount of fuss and delay, but ultimately ensuring your overall safety long term.

Compression shorts or jockstrap?

Whether you choose compression shorts or a jockstrap for your groin protection may be solely based on your personal preference!

A jockstrap is perhaps the most common style and a firm favorite for many over the years. 

Some find jockstraps allow for increased freedom in movement and less restriction, and so are a preferred choice for many athletes in a wide range of activity types.

But compression shorts are now becoming increasingly popular alternatives to jockstraps.

Designed to reduce restrictions of movement, these are the all in one solution which comes in a wider choice of styles. 

Better still, many users like being able to wear some of the short types without needing to cover them up, as you have to do so with many jock strap varieties.

How to pick the right size

It’s strongly recommended that you look to each individual supplier when selecting that best size for your crotch protector.

Sizes vary with every manufacturer, so what may be a small in one product, can seem like a medium when bought from another supplier. 

However, to ensure the perfect choice throughout use, we recommend paying attention to:

Comfort and fit – As well as fitting snuggly and neatly, you will need to be able to move around freely while the cup remains in place.

However, this will also mean assuring the inner material for your shorts or jockstrap is designed with maximum comfort in mind. 

Those boasting multi-layered padding work well here as do those with gel inserts to keep you remaining cool and fresh.

Protection – It goes without saying that you’ll need to ascertain the right size of boxing cups to be sure of continued protection. 

If your choice is too tight, it will pinch your skin and leave marks, making it extremely uncomfortable in use. 

But too big a size and you won’t be afforded the necessary protection due to shifting. 

Thus, the correct size will be one that keeps the cup in place at all times and is so comforting, you’ll soon forget it’s on!

Which is the best groin guard for MMA?

For MMA purposes, the best groin guard is one that mentions MMA in its description. Our choice would, therefore, be the Diamond MMA Athletic cup groin protector.

Which is the best groin guard for boxing?

For boxing purposes, once again, we suggest considering those groin protectors that state boxing in their product’s description. Though there are more choices available here, we would suggest the Title Boxing groin guard.

Groin Protector Summary

By ensuring a safe level of groin protection each time your train or spar, you ultimately protect yourself from some powerful and harmful blows.
