Blue rash guard: belt meaning, models and sizing
What does the color blue represent in BJJ?
In Brazilian Jiu-Jitsu, blue is not an insignificant color. It officially marks the transition from white belt to blue belt, a symbolic step that confirms you have mastered the basics of the game: escapes, postures, first submissions, and ground survival. The blue rashguard is thus the emblematic garment of practitioners who reach this first rank, and it continues to accompany many competitors beyond that out of loyalty to this transitional color.
Beyond BJJ, blue also remains one of the favorite shades of grapplers and MMA practitioners, as it pairs perfectly with black, white, and even colorful shorts. It's a color that inspires technical maturity and concentration. At Hustle Fightwear, we design our blue rashguards to highlight this symbolism without sacrificing performance.
IBJJF & CFJJB regulations for the blue belt
If you are a blue belt and planning a no-gi competition, the rules are strict: your rashguard must be either predominantly blue with at least 10% visible blue, or predominantly white with at least 10% blue, or black with at least 10% blue. 100% black rashguards without any blue, or neutral colors like grey alone, are refused at IBJJF and CFJJB weigh-ins.
Our advice: choose a rashguard with a clearly visible blue background. This is the safest choice for passing equipment checks and also the most identifiable for referees during the fight. To delve deeper into the subject, see our dedicated article on blue belt rashguard regulations in no-gi competition.
How to choose the right size blue rashguard?
The size of a rashguard is crucial: a rashguard that is too loose will not provide compression and will float during transitions. Too tight, it will restrict your shoulder and core movements. The right fit is a second skin without compressing your breathing. Measure your chest and waist circumference, then cross-reference them with our size guide.
If you are between two sizes, choose the smaller one: the fabric will stretch slightly after two or three washes. All explanations are in our complete article: what size to choose for a rashguard.
Hustle Fightwear blue models
In the Hustle Fightwear rashguard collection, several items feature blue prominently. The Competitor V2 in its blue version is our flagship model for competitors: premium compressive fabric, clean design, compliant with IBJJF and CFJJB standards. It's the pro option for those aiming for the podium.
For daily training, we also offer blue/black and blue/white models that provide a more striking visual contrast. Hustle's Nation Drops, especially the series dedicated to certain countries, regularly incorporate the color blue into their designs as a nod to national flags. Short sleeves or long sleeves? The choice depends on your style: we discuss it in long sleeves or short sleeves: which to choose?
Care: preserving the vibrancy of blue
Blue, like all bright colors, can lose intensity if not properly cared for. Wash your rashguard inside out, at a maximum of 30°C, with a mild detergent and no fabric softener. Absolutely avoid bleach and tumble drying: heat destroys technical fibers and fades the color. Air dry it, away from direct sunlight.
If you want to delve deeper into the care routine, see our complete guide how to wash a rashguard. A well-maintained rashguard can easily last 200 to 300 mat sessions without losing compression or color.
