What’s a BJJ rash guard?
A rash guard in Brazilian Jiu Jitsu refers to a fitted athletic shirt, usually made from a blend of stretchy polyester and spandex. A rash guard is worn in no gi jiu jitsu in place of a t-shirt, and it can also be worn underneath a gi jacket. It’s main purpose is to prevent the wearer from getting mat burn or scratched and cut when rolling, and is preferred over a t-shirt because of its snug fit and quick drying properties.
BJJ rash guards come in both short and long sleeve versions, and may feature your rank color, artworks, or both.
What features do the best rash guards have?
High quality BJJ rash guards generally have many of the features below:
Flatlock stitching refers to a type of flat fabric join where there is no fabric bulk at the seams. The inside of a rash guard with flatlock stitching won’t irritate you as you drill and roll, and flatlock stitching can make a rash guard stronger. Stitching on a BJJ rashguard might also be reinforced to make it more durable.
Four-way stretch fabric
High quality rash guards need to be made of a stretchy enough material to last hours of training, during which time it’ll get caught on fingers, rolled up and accidentally tugged on. For this reason most quality rash guards are made from a fabric that stretches both length and widthwise. This is usually a blend of polyester and spandex (or lycra/elastane as it’s known outside in the US). Many high quality rash guards will use a blend of 80% polyester and 20% spandex, but some brands might use different proportions of each.
Sublimation is a special type of printing process which uses heat and pressure to embed ink into a polyester fabric or surface. This means sublimated designs won’t peel or fade, which is perfect for BJJ where your rash guard will be constantly subjected to tough and wet conditions each week.
Rubber or silicone waistband
Many high quality rash guards also have an anti-slip band that runs along the bottom waist portion of the rash guard. These are usually made from silicone or rubber and prevent the rash guard from riding up during drilling or rolling.
Multipanel construction refers to the rash guard being made up of individual panels which are stitched together, rather than a smaller number of larger fabric panels. This makes the rash guard more comfortable when moving.
The best rash guards feature attractive designs or artworks in addition to being functional and durable. Some brands will even work with noted artists to create unique designs.
For those thinking of competing in International Brazilian Jiu Jitsu Federation (IBJJF) tournaments, you’ll want a rash guard that is advertised as being IBJJF compliant. This means the rash guard will have at least 10% of your rank colour on it.
Some of the best rash guards also have additional features like mesh fabric around the armpit areas for extra ventilation, limited edition artworks, personalization options or anti-microbial fabric treatments.
What’s the difference between a compression top and a rash guard?
Compression shirts can be very similar to rash guards depending on the type of compression shirt and fabrics used.
The main differences between a compression top and a rash guard is that compression tops may have a tighter fit and may not feature reinforced stitching like a rash guard designed for BJJ or MMA.
In addition, a compression top is aimed at a wide variety of general sports, so won’t usually feature designs related to BJJ.
There are many jiu jitsu practitioners who wear compression tops as an alternative to rash guards. They often recommend brands like Under Armour or cheaper alternatives like the TSLA Compression Shirt, which are both tops made from the same materials as BJJ rash guards.
If you opt for a compression top rather than a rash guard, be sure to check that the fabric is still a blend of polyester and spandex (known as elastane/lycra outside the USA). This will ensure that you don’t buy a top with cotton in it, which will keep moisture in instead of wicking it away.
Frequently asked questions
Do rash guards stretch over time?
Quality rash guards won’t stretch significantly over time, although they will become a little looser with frequent use.
Should a rash guard be tight?
A rash guard for jiu jitsu should generally be tight but comfortable. Looser rash guards can ride up more often and get caught or stretched accidentally when rolling. IBJJF rules specify that rash guards must be skin tight:
