Un bon rash guard de JJB colle sans plis et descend sous la ceinture du short.
Visez un tissu d’environ 230 g/m², extensible dans les 4 sens, à coutures plates.
Choisissez une impression par sublimation : le motif est dans la fibre et ne craquelle pas.
En IBJJF no-gi : fond noir ou blanc avec au moins 10 % de la couleur de ceinture. En ADCC, tout passe.
Prenez votre taille habituelle : entre 2 tailles, la taille en dessous en manches longues, qui taillent grand, et la taille au-dessus en manches courtes.

Choosing the right fit and size

To fully benefit from a rashguard, it’s crucial to select the right fit and size. Here are some tips to help you make the best choice.

Taking your measurements

The first step is to take your measurements. Use a measuring tape and measure the following areas:

Chest circumference – Measure around the widest part of your chest.
Waist circumference – Measure just above your navel, where your natural waistline is.
Hip circumference – Measure around the widest part of your hips.

Checking size charts and measurement guides

Once you have your measurements, compare them to the size charts provided by different manufacturers. At Rashu, we specialize in rashguards! Feel free to check out our wide range of models.

Choosing based on your budget

The price of a rashguard varies depending on the brand, materials used, and integrated technologies. It’s essential to find one that fits your budget while ensuring quality and durability. However, a high-quality rashguard will rarely cost less than $60.

While it may be tempting to opt for a cheaper rashguard, it could end up being more expensive in the long run if you have to replace it frequently due to poor quality. Investing in a high-quality product from the start can be more cost-effective over time.

Choosing based on your aesthetic and practical preferences

Lastly, choosing the right rashguard should also align with your aesthetic and practical preferences. If you love bright colors or unique patterns, why not go for a model that reflects your personality?

Choosing the right rashguard for Jiu-Jitsu involves considering several factors. Take the time to carefully evaluate all the characteristics to make an informed decision and fully enjoy the benefits of this essential piece of gear in Brazilian Jiu-Jitsu!
