• Cool Waterproof Backpack designed by Isami in Japan for martial artists.
  • It offers plenty of room and smart compartments so you can carry all the gear needed for one day of training.
  • All straps are reinforced and adjustable so the backpack stays comfortably close to your body when you are on the move.

☔ The Isami Waterproof Backpack is our best selling bag for martial arts. This large capacity bag (37.5 ltr) can store all your training gear and keep it protected from the rain. All external zippers are water resistant with rubber sealing closure.
🎒 The bag's main compartment can be zipped closed to create two partitions. This is perfect for 
separating clean and sweaty gear, for example. You can easily access this main compartment from the top or from the bottom of the bag, depending on your needs.
👊 And there's more: the bottom partition is sponge-padded and just the right size to fit a Karate or Boxing Head Guard such as the famous Kudo Daido Juku Helmet.
🔖 The front of the bag features a large pocket in A3 size with a side zipper for easy access. This is where you can store your e-reader and some magazines, for example.

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.

Brandon M. Tennessee, USA

Fast shipping. Tee quality and design definitely worth buying. Interesting part was the fantastic services provided by the support team so I could surprise my loved one. Truly appreciated.

I have purchased 4 belts through ChokeSports. Everyone of them was of exceptional quality and the workmanship was incredible! The customer service and ease of placing my order was awesome.

Ken G. Colorado, USA

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.
