It doesn’t matter which type of martial art you’re involved in, wearing a groin guard is essential. That’s why we’ve included the best groin cups for BJJ, Muay Thai, MMA, and boxing. Some will be better suited for specific arts, whilst some can be used across all combat sports.

Comfort and protection are key when picking, that’s what we’ve focused on in our reviews. So, here you have the 10 best groin guards available online.

Winner: Diamond MMA Groin Cup With Compression shorts

Diamond MMA Groin Cup with Compression Shorts

Our winner on the list and in our opinion, the best MMA groin guard, is the Diamond MMA Athletic cup.

This isn’t only a groin cup, you also get a pair of compression shorts. It’s the shorts that hold the cup in place with a specially designed pocket. The compression shorts use military-grade elastic combined with premium spandex. That’s why the price is higher than others, but that’s why it’s the best groin cup on the market.

Diamond MMA doesn’t mess around with many colors, sticking to all black with blue seams. It does come in lots of sizes though. Here’s the full range of adult and youth waist sizes:

  • Youth Medium 23-24″
  • Youth Large 25-26″
  • Youth X-Large 26-29″
  • Small – 27-30″
  • Medium – 31-34″
  • Large – 35-38″
  • X-Large – 39-42″
  • XX-Large – 43-48″

The shorts boast a four-strap jock system design inside. This works to keep the cup in place, thus preventing any movement. As it’s not a typical jockstrap it’s even more comfortable.

For further safety and comfort, these shorts are finished with a polycarbonate core. Your groin muscles and nerves will also come under less stress when wearing it all. The material is rigid but flexible, it’s also that same material that is used in bulletproof glass!

Diamond MMA has won awards for its design. The cup is also approved by doctors and urologists. There are even videos of people getting hit in the balls and still being fine.

Expect to see more from Diamond MMA too, as they now even make BJJ rash guards and other items. This excellent brand is growing!

Pros:

  • Approved by doctors and urologists
  • Military-grade materials
  • Uncompromising comfort and safety combined

Cons:

  • A higher than average price tag

Many professional athletes now use Diamond’s MMA cups as they’re approved by doctors.

Mueller Athletic Supporter With Flex Shield Cup

Mueller Athletic Supporter with Flex Shield Cup

Mueller’s Athletic Supporter and cup differ slightly in design to the other models. This is a support with a flex shield cup, rather than compression shorts. It’s more like the jockstrap guards. 

The cup is grey/white and the supporter is all white. This model is an adult medium, but there are also smaller and bigger sizes. Here’s a size chat that Mueller offers.

Mueller claims that when the cup is placed correctly it reduces the number of injuries in the groin area. The cup itself has soft edges for increased comfort, and this allows the cup to flex slightly.

Groin Protector FAQ

Is a groin protector necessary?

Yes, when sparring and in competitive fights, a groin protector is necessary. Trust us when we say you don’t want to forget to wear it. Although sparring is done with training partners, kicks and punches can land anywhere!

You can recover from one hit to this area, but imagine it happens more than once in the same session…you don’t want that. That’s why this should be something that you invest in. Even if you don’t want to spend out on the compression short models, get a decent jockstrap and cup.

Compression shorts or jockstrap?

Picking between compression shorts or a jockstrap is down to personal preference.

A jockstrap has been the most common style and a firm favorite for many over the years. But compression shorts are now becoming very popular. Not only do they have pouches for the groin cup, but they also keep your muscles warm. So they also help reduce muscle injuries.

Then, there’s the argument that jockstraps allow for increased freedom in movement. We’d argue that once you’ve had compression shorts on for a while you don’t even notice them. Still, this comes down to personal preference.

How to pick the right size

The actual size of the groin cup doesn’t change much, generally, you get adult or youth size. Size matters when buying a cup along with a jockstrap or compression shorts. This is because both of these are measured by waist size.

But, cup sizes can vary depending on which brand you buy. A cup shouldn’t be too big or too small.

Here are more details on what we pay attention to:

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

So, the inner material of your shorts or jockstrap needs to be designed with comfort in mind. Ideally, the groin cup will have a soft rim so that it reduces movement. 

Ventilation holes are great if the cup isn’t going to fit into a pouch. Then, groin protectors with multi-layered padding and gel inserts ensure freshness. These larger ones are generally for boxing though.

Protection – You’ll need to get the right size of cup to be sure of continued protection. 

If your choice is too tight, it will pinch your skin and leave marks. But too big a size and you won’t be afforded the necessary protection due to shifting. If you have either case you won’t be using it for long.

The correct size will stay in place at all times and is also comforting.

Which is the best groin guard for MMA?

For MMA purposes, the best groin cup is one that mentions MMA in its description. Our choice would, therefore, be the Diamond MMA Athletic cup groin protector. This model is light, and can even withstand bullet shots!

Due to its design, and a great fit with shorts or a jockstrap, it’s also a perfect cup for BJJ, and Muay Thai.

Which is the best groin guard for boxing?

For boxing training, the best groin protector is the Title Boxing groin guard. Title is well known for its boxing gear, and this product is another top range item. You’ll be able to use this in sparring and not worry about low punches to the groin and lower abs area.

Groin Protector Summary

As we’ve already stated, getting the best groin protector available is a smart choice. Even if it costs a bit more, it’s worth not getting injured in that delicate area. 

Your choice will depend on which primary combat sport you train in. The best groin cup for BJJ, MMA, and Muay Thai is hands down the Diamond MMA cup. As you’ve seen, they offer three products, the groin cup on its own, jockstrap + cup, or compression shorts + cup. The compression shorts are our number one choice, but the others are also good.

For boxers, Title Boxing or Pro Impact’s groin protectors are both good. The Title Boxing model offers a bit more protection so we’d go with that one first.

That’s all for now, make sure to protect these important areas!
