NESF Boston - The Most dedicated No-Gi Jiu-Jitsu School in Greater Boston


The martial art of Brazilian Jiu-Jitsu has a time-honored tradition of awarding belts to signify rank, acknowledging students’ many stages of development. As No-Gi Jiu-Jitsu gained popularity, some students removed their gis entirely, effectively excluding themselves from this traditional ranking system. At NESF Boston, we uphold the ranking tradition, providing ranked rash guards in place of belts to recognize the knowledge and skills built through dedicated practice.

Students earn their white rash guard with their first step onto our mats. There is a boldness in entry into martial arts – starting something new can be intimidating and it deserves recognition. The white rash guard symbolizes an open mind and a willingness to learn. A student’s time at this rank is characterized by novelty and exposure to the various elements of No-Gi Jiu-Jitsu.

The green rash guard is given to students who have a basic familiarity with the fundamentals of the art. This is the first milestone of technical progress, indicating an initial dedication to the study and practice of Jiu-Jitsu.

Though it is not found in every Jiu-Jitsu academy, the green rash guard marks a significant step in a martial artist’s journey.
