Official IBJJF Standards for the Dedicated Grappler
Your belt is more than just a uniform accessory; it is the physical representation of thousands of hours on the mats. The SMAI Brazilian Jiu-Jitsu Belt is engineered to honor that effort with a construction that withstands the rigors of daily rolling. Unlike generic martial arts belts that become limp and threadbare quickly, this belt is built with a resilient Jute core, providing a firm structure that holds a knot securely—even when you are deep in guard or scrambling for position.
Designed strictly to International Brazilian Jiu-Jitsu Federation (IBJJF) specifications, this belt features the mandatory 4cm width and the distinct black graduation bar (12cm) for stripe progression. Whether you are a white belt stepping onto the mats for the first time or a brown belt preparing for the final hurdle, this belt ensures you look the part with professional, competition-ready polish.
Why Choose the SMAI BJJ Belt?
-
Jute-Filled Core: The internal jute material provides superior tensile strength and stiffness compared to standard felt. This ensures the belt maintains its shape and integrity, resisting the "rope-like" deterioration common in cheaper belts.
-
IBJJF Certified Design: Manufactured with the precise 12cm graduation bar (black block) required for rank stripes, making it fully compliant for all IBJJF tournaments globally.
-
100% Colour-Fast Technology: Constructed from high-grade poly-cotton that locks in the dye. You can sweat profusely or wash your belt without fear of the color bleeding onto your expensive white Gi.
-
Comprehensive Sizing: Available in the full spectrum of BJJ ranks, including the complete youth system (Grey, Yellow, Orange, Green groups) and adult ranks (Blue, Purple, Brown, Black).

Sambo Store Pro-Tip
The Jute core in these belts makes them incredibly durable, but it also means they start out stiffer than a cheap cotton belt. To prevent your belt from untying during rolls in the first few weeks, we recommend using the "Superlock" or "Hollywood" knot technique. This flat-lying knot works with the stiffness of the jute to create a secure hold that rarely comes undone, allowing you to focus on your passing game rather than constantly re-tying your Gi.
