Should You Wear a Rashguard Under Your BJJ Gi?

If you’re a new student at a BJJ academy it’s likely that your coach will expect you to wear a rash guard underneath your Gi. This is to prevent you from getting mat burns or other skin infections from the rough surfaces of the training mat. It’s also a way to help your teammates see where you’re going on the mat. Some gyms won’t make this a requirement but it is the norm in many larger chain academies.

bjj gi are made from different fabrics and the quality of the Gi you choose will make a difference in how long it lasts. It’s best to buy a gi that is known for quality and durability. You’ll also want to look for a gi that is lightweight so you can move more easily on the mat.

The gi is a traditional uniform of jiu-jitsu and other martial arts. It’s composed of a jacket and pants that are both designed to help you grip your opponent and submit them with grappling techniques. In a gi competition, athletes are not allowed to compete with an old or damaged gi. They must be clean and in good condition. This means that the pants must not be torn or have any holes in them. The top must not be too loose and it should have a good collar. The sleeve length must be the same as your rank belt and not extend past the knee.

You may not be required to wear a rashguard under your gi but it’s a smart idea. This baselayer compression t-shirt helps with blood flow, keeps you warm, and protects your skin from mat burn or other injuries. It’s usually made from a stretchy spandex material and can come with either short or long sleeves. The choice is up to you and it depends on your preference and the weather where you live.

While not everyone will need a rashguard under their gi, some people will find it very helpful. This is especially true if they are new to BJJ or in warmer climates. A rashguard will also keep the fabric of your gi from stretching out too much and it’ll give it a longer lifespan.

If you’re new to the sport it’s not uncommon for your gi to get stretched out or even ripped during training. In that case, you might want to invest in a new rashguard so you can continue to train without having to worry about your t-shirt getting worn out or ruined.

BJJ rashguards are also useful for no-gi training as they will allow you to grab onto your partner’s legs more easily than you would in a gi. This will give you a distinct advantage in certain positions and submissions but it’s not something you can count on all the time.

BJJ rashguards can be purchased online or at most major retailers. It’s best to use a rashguard size guide to ensure you buy the right one. The guide will take into account your height, weight, and girth to determine the ideal size for your body. The brand of rashguard you purchase will also play a role in how it fits. There are a number of options out there but you should stick with a reputable brand.
