Today, I’ll review the BJJ Rash Guard I have worn the most this year: The RDX Rash Guard.

It was also the first Rash Guard I ever bought. I remember how proud I was when it finally came.

Now, I have multiple Rash Guards and know how to compare the RDX Rash Guard with other Rash Guards on the market.

This one stands out from the competition in many ways. I’ll give you an honest look at this product. So read along and decide for yourself whether it’s worth buying.

A Complete RDX Rash Guard Review

I’m happy with my RDX Rash Guard. It’s rare to get such a high-quality product for such little money.

In the following, I’ll detail the pros and cons of the RDX Rash Guard.

Material/ Quality

I have bought other Rash Guards in similar price ranges, such as the Lafroi Rash Guard. And I have to say I haven’t seen one that has better quality than this one.

What stands out is that this Rash Guard feels heavy, but it’s still thin. It doesn’t feel suffocating when wearing it. It’s breathable and resistant to all the pulling and grabbing of Brazilian Jiu-Jitsu.

The material stretches well and is flexible enough for all movements.


The Design is simple. It looks similar to a compression shirt. It doesn’t have the typical crazy and unique designs of other BJJ Rash Guards.

That’s why the RDX Rash Guard falls into this price range. They didn’t compromise on quality and, therefore, on Design. In contrast to the Lafroi Rash Guards, they compromised on quality and focused on Design.


My size is usually between a Large and an X Large. I ordered my RDX Rash Guard in X Large, which fits perfectly. It’s not too tight and not too loose. So if your size is also in between and you’re unsure which one to order – size up.


I have been wearing this Rash Guard for a while now. Sometimes for multiple hours. And it’s comfortable. It keeps me warm, protects me against rashes, and is breathable.

I also decided to wear this one for my first BJJ tournament because it’s so comfortable.

The only downside is that it doesn’t have a waistband or wristband.

So, as you can see in the picture on the right, it tends to get loose around the wrist area.

This bothers me at times, but maybe I’m just too sensitive.

Breathability & Sweat-Resistance

This Rash Guard is so breathable that I also started wearing it in my free time. I wear it for hiking, walking, or hanging out. It keeps me warm and comfortable.

I have to say, though, that when I’m drenched in sweat, I own Rash Guards, such as the Hayabusa Rash Guard, that absorb the sweat better.

The RDX Rash Guard absorbs the sweat, but if you grapple for some time in a hot climate, the sweat will get to you.

Nonetheless, this happened to me only twice since I had it. For regular practice, you don’t have to worry about it.


The price for the RDX Rash Guard is low compared to other products. The value it offers for the money you spend is amazing.

It’s a reliable Rash Guard. It didn’t rip, the brand logo still has not faded away, and the material didn’t take any damage.

Even after multiple washes, it looks and feels like new. So, if you want a high-quality product at an affordable price, the RDX Rash Guard is the one to go for.

Alternatives To RDX

In case you are looking for more flashy designs in the same price range, I’d recommend checking out the LAFROI Rash Guards. They have some amazing designs; the quality of their Rash Guards is not that high, though.

And if you’re willing to spend a bit more for your Rash Guards, I’d go for the Hayabusa Rash Guards. They have premium quality and are super reliable. I love wearing them.

Final Words

So, this is a top product in terms of quality and price. But if you’re into flashy Design, you should go for other Rash Guards on the market.

I like my RDX Rash Guard just because it’s so reliable. It offered so much value.

I have worn it more than I can count, and it still holds up. I like how it fits, and I wear it for activities outside of Jiu-Jitsu.

So, I’d recommend buying the RDX Rash Guard for its amazing price-to-value ratio.
