• This is our best selling soft black belt because it combines rigidity, weight and durability. 
  • The belt ends fall naturally after only a few training sessions to give that cool black belt look.
  • For the ultimate level of customization, use our belt builder tool to design your new belt with beautiful embroideries and stitched degrees.

➡️ The Isami F-450 Black Belt from ChokeSports is handcrafted in Japan with specs to ensure it's easy to tie and keep the knot. We actually use a stiff core in order to make the belt easy to tighten and hold the knot. When this belt starts to fray, the white inner core will show. It ages beautifully without losing its functionality, just like you'd expect. Recommended for Karate, Aikido, Judo etc. Get it now!

SHIPPING & RETURNS
⏲️ It takes 20 work days to custom make your new belt, but we also offer a rushed service (10 work days) for urgent orders. 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: we'll custom make the belt exactly the way you want it!

BELT WIDTH: 42mm, 45mm, 50mm
Now you can choose how wide your Isami Black Belt should be. The standard belt width is 42mm (1.65in) but we also make wider variations that are 45mm (1.80in) and 50mm (2.00in). They are especially popular with bigger fighters/instructors who need a belt that will match their large frame.

INTEGRATED EMBROIDERIES
Our Isami Black 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. The final product is unique and stunning!

DEGREES
Show your hard earned rank with stitched degrees that will never fall off, unlike the usual sports tape stripes. You can choose the color of your stripes to perfectly match your martial art and attitude.

BELT SHRINKAGE: 7.5%
Your new Isami Black Belt will shrink naturally due to humidity and sweat. That's why we say in Japan that "the fabric is alive". The estimated shrinkage rate for this belt is 7.5%. Please take this in consideration when selecting your optimal belt size.

BELT WASHING INSTRUCTIONS
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.
