🧼 Washing & Shrinkage
Expect Some Shrinkage: Your gi isn't pre-shrunk. It may look a bit large at first, but will adjust to the perfect size after 2-3 washes.
Washing Instructions: Wash at a maximum of 40°C. Avoid bleach to protect the fabric's integrity. Dry cleaning is safe.
👕 Drying
Hang Dry Method: Use separate hangers for the top and pants. Dry in the shade to maintain its shape.
Tumble Dry Caution: If using a tumble dryer, stop at 80% dryness to prevent excessive shrinkage. Then, hang it to finish drying.
🩸 Stain Management & Rotation
Quick Action for Stains: Wash immediately after practice if stained, especially with blood, to avoid permanent marks.
Rotation Strategy: Like many of our customers who train frequently, consider rotating multiple gis. This ensures a fresh gi for each session and extends the life of each one.

Overall rating: 4.9 / 5 from 18 reviews.
Great Japanese gear. Excellent quality, especially comparing to Pakistani cotton and hands. Great attention to detail. Stitching is perfect. Pants got to true size after a couple of washes.
Store owner replied:
Hello Mikhail,Thank you for the great review and for sharing a photo of yourself wearing the Isami Karate Gi Kumite — it looks fantastic on you. It’s always awesome to see our customers training in authentic Japanese gear.We’re really glad everything came together in the end, especially with DHL Express getting it from Japan to the UAE in just two business days. Your feedback on the craftsmanship, stitching, and fabric quality perfectly captures what sets Japanese-made Isami gis apart, and your note about the pants fitting true after a few washes is especially helpful.We truly appreciate the recommendation and your trust in ChokeSports. Looking forward to supporting your training again in the future.Best regards,The ChokeSports Team

K-450...a must buy!. This is my first order from Chokesports and I'm really impress: great communication with the customer, fast shipping, and top quality karate gis...what do you want more? The Gi respects faithfully the size chart and the specs, and it has premium feel when you wear it, so I have to say that...that's my first Isami Gi but it won't be the last one! Well done Chokesports and Isami!

First time purchasing a pre bleached Isami. Quality as usual. Gi bottoms are heavy so purchase different pre bleached Isami gi bottoms if you prefer the traditional heavy top, lighter bottoms combo. This K-450 would be ideal for competition kata.
Store owner replied:
Hello Leon,Thank you for the 5 stars and for choosing the Isami Karate Gi Kumite. We’re glad to hear the quality met your expectations—Isami always delivers that level of craftsmanship.We also appreciate you pointing out the heavier gi bottoms on the K-450. That’s really helpful insight for other customers deciding between the traditional heavy top and lighter bottoms combination. And you’re absolutely right—this gi works great for competition kata.If you have a moment, we’d love to see a photo of your new gi in action. Feel free to share it here or tag #chokesports on social media.Best regards,The ChokeSports Team

i have never ever in my life felt some high quality gi such as this K-450/i'd like to point out few things: first, i wanna thank for Connor. he was so patient woth me and helped me alot wish choosing my gi. in addition he was extremely professional.second, id like to thank you Lisa for being so kind with all the shipping process. i def. felt like im doing business with family who attached to their business and not just a representative who trying to "close the deal".third (and this is the most crucial one). i would highly suggest to emphesize the fact that the height in the size chart is a reccomandation and bettter go with the actual measurments. ill tell why. im 5"10 its like 178 CM if i go by the height ill need to get size 6 maybe. (175 CM) but when i measured old karate gi i fouind that my measurments fits size 5 perfectly. when i recieved the gi i put it on and it was pretty big but thats beacuse its before shrinkage. never washed. i strongly believe after 1 or 2 washes it will fit perfect. so the height guide is not accurate. i will add pic of me before and after wash so u guys can use it as a perfect example to show to whoever asking you. see, this is very expensive product and its very important to avoid any mistakes, i mostly never measure but in this case i knew it is extremely premium and expensive so i wanted to to it right; thank god i toos exact measures cause if not i would be end up with pretty baggy gi and last thing i wanna do it take it to private tailor.so bottom line you guys are awesome, shipping was so fast, all costumer service was off the charts, very professional and i will def. be your costumer in the future. thank you guys and have a great week.im very satisfy

Shalom Zeituni,WOW right back at you — thank you for such an incredible and detailed review of the Isami Karate Gi Kumite (K-450).We’re truly grateful for your kind words and especially for taking the time to explain your sizing experience so clearly. Your point about prioritizing actual measurements over height recommendations is extremely valuable, particularly for a premium, made-in-Japan gi like this. You’re absolutely right that shrinkage plays a key role, and your willingness to share before-and-after photos will help many future customers make the right choice with confidence.Connor and Lisa will be very happy to read your comments. We take a lot of pride in offering patient, honest guidance and treating customers like family, so it means a lot that this came through in your experience.Thank you as well for trusting us with such an important purchase. We’re thrilled to hear the shipping speed, service, and overall quality met your expectations, and we truly look forward to welcoming you back as a customer again.Have a great week and thank you again for your support.Best regards,The ChokeSports Team

Feel free to share it here or tag us on social media with #chokesports.Thanks again, and we look forward to serving you again.Best regards,The ChokeSports Team
This is a very good gi, especially for those like myself with short legs and large glutes. It is light and comfortable, allowing for easy movement. The gi has no ties on the jacket to secure it in place and it can fly open, even with a tight belt. That is the reason for 4 stars rather than 5. I must say the shipping on this product was extremely fast. It took less than a week to get this gi from Japan to the U.S with standard (and free) shipping. Very impressive!
Store owner replied:
Hello Joseph,Thank you for the detailed and honest review of the Isami Superior K-450 — we really appreciate you taking the time to share both the positives and the drawbacks.We’re glad to hear the fit works well for your build and that you’re enjoying how light and comfortable the gi feels in movement. Your feedback about the lack of inner jacket ties is completely fair, and it’s helpful for other customers who may be deciding between models. That design choice is true to traditional kumite specs, but we understand how it can be a downside depending on training style.It’s also great to hear the shipping from Japan to the U.S. impressed you, especially with standard free shipping arriving in under a week.Thank you again for your thoughtful feedback and for choosing ChokeSports. We hope to support your training again in the future.Best regards,The ChokeSports Team
Great customer service and got my gi much earlier than expected.

Hello Lubos,Thank you for the great review and for choosing the Isami Karate Gi Kumite.We’re happy to hear the gi arrived much earlier than expected and that our customer service made a positive impression.

Im very happy with the GI, i can tell easily that it is a quality product, but sadly its a little pricey which i think is maybe equal to the quality but the shipment fee is quite high in my opinion therefore i get hesitant before making my order.
Store owner replied:
Hello Mohsen,Thank you for your honest review and for sharing your experience with the Isami Gi.We’re very glad to hear you’re happy with the gi and that the quality stands out to you — that premium, made-in-Japan craftsmanship is exactly what Isami is known for. We also appreciate your openness about the pricing and shipping costs. Your hesitation is completely understandable, and your feedback is fair. Shipping directly from Japan, especially with fast and reliable carriers, does add to the cost, but we always aim to balance that with authenticity, quality control, and dependable delivery.Thank you again for your trust and for choosing ChokeSports. We truly appreciate your feedback and hope to support you again in the future.Best regards,The ChokeSports Team
Karate Gi from choke sports ,arrived in time, it is really great product For years I have different Gi`s ISAMI is best feeling Gi on market. Thank You Choke Sports
I got this dogi for my Kyokushin class. Quality is unsurpassed, as all Japanese products I bought during the years. I have other Japanese dogis and all are nice. this one is better fitted to Kyokushin training. The jacket is longer than in other brands, a thing that I particularly like for I am tall. Thick canvas that feels like medium in your body. Crisp and noisy as it should be. The pants: best Karate pants ever. The fabric is different and they really feel like wearing nothing. Same fabric weight (I think) but different texture makes for really free movement. I look nice on it. I feel comfortable in it. What else can I ask for?
Store owner replied:
Hello Josep,Thank you for such a detailed and thoughtful review — we really appreciate you taking the time to share your experience with the Isami Karate Gi Kumite.It’s great to hear how well it works for your Kyokushin training, especially the longer jacket length and the way the cut suits a taller build. Your description of the fabric, the crisp feel, and especially the pants made us smile — “best Karate pants ever” is high praise, and exactly what Isami aims for with this model.We’re glad the gi makes you feel comfortable and confident on the mat. If you have a moment, we’d love to see a photo of it in action. Feel free to share it here or tag us on social media with #chokesports.Thank you again for your feedback and for choosing ChokeSports.Best regards,The ChokeSports Team
