Now you can order the Isami BJJ Black Belt with White Bar! According to IBJJF regulations, the 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.

Our custom made belts feature integrated embroideries. This is the most premium method of embroidery and also the most resistant. We embroider the fabric first and then we make the belt. There will be no trail on the reverse side, but the belt stitch lines will be over the embroidery.

In Japan it is uncommon to wash the obi martial arts belt. However many of our international customers like to wash their belts. We recommend hand washing (with hand soap) and hang drying in the shade. Please note that regular washing will accelerate the belt's aging process and might cause it to shrink further than estimated. It will still be functional and last for many years though.

  • It takes us approximately 10-15 work days to custom make your new belt exactly the way you want. The whole process is handmade and we always have many orders waiting in line. We will send you a completion estimate a few days after the order is placed so you know when it will ship.
  • Because these belts are made to order and unique, they cannot be returned or exchanged. So please make sure to double check all the details before completing your order. Once we start working on the belt, no changes will be accepted. All sales are final.
  • We guarantee the wait is very much worth it and that we'll custom make the belt exactly the way you want it!

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.
