According to IBJJF regulations, the BJJ black belt must have a 10cm/4in rank bar on one end. We give you the option to choose what your rank bar will look like: the classic red with white bars on the ends, plain red or even plain white, as some top competitors have used lately in competition. You can also request embroidered degrees that will never fall off, unlike the usual sports tape stripes. We stitch white degrees on the red rank bar and black degrees on the white rank bar.

A0 255cm / 100in, A1 275cm / 108in, A2 295cm / 116in, A3 310cm / 122in, A4 325cm / 128in, A5 340cm / 134in + Custom Size (you pick the ideal belt length for your body type or taste). Please allow 2cm/0.8in margin of error due to humidity and shrinkage.

You can customize the Isami BJJ Black Belt Premium with beautiful embroideries and turn it into a unique item. We have a reputation for making the most beautiful belt embroideries and we guarantee you will be impressed.

What Customers Are Saying About Chokesports

I've always had my eye on RVDDW and Isami brand gear but wasn't sure about how to order in the US. ChokeSports made the process extremely easy and the shipping was amazingly fast. Extreme recommend to anyone on the fence.

I'm always happy to open the package to discover another new obi belt. The quality is still the best, delivery time still there, and most important the service is number one. Very dedicated to the client.
