Kumite Size Chart

Please note that SMAI WKF Approved uniforms have a different cut from their Classic Student uniforms.

The Kumite Gi and Senshi Gi cuts have longer jackets. The Kata Gi is a Japanese style cut with shorter pant cuffs.

We recommend that you choose sizing based on your height to find the right fitting karate uniform (please go up 1 size for fuller figures or 1 size down for a tighter fit).

The Ultimate 2-in-1 Competition Advantage

For the elite Kumite athlete, managing equipment during travel and tournaments is a logistical challenge. Carrying multiple heavy uniforms to cover both "Aka" (Red) and "Ao" (Blue) requirements takes up valuable luggage space and adds unnecessary weight to your kit bag. Standard uniforms force you to switch entire jackets between bouts, breaking your focus and adding stress to your warm-up routine.

The SMAI Inazuma RX solves this problem entirely with its revolutionary reversible engineering. This is the ultimate travel-friendly solution: a single, ultra-lightweight jacket that flips instantly from Red to Blue shoulder detailing. Built on the chassis of the legendary Inazuma fight gi, the RX maintains the featherlight 6oz microfiber construction you rely on for speed, while cutting your packing requirements in half. It is the definition of efficiency for the travelling competitor.


  • Feature: Reversible Shoulder Design
    Switch effortlessly between Aka and Ao competition requirements by simply flipping the jacket inside out. This 2-in-1 design eliminates the need to buy or pack two separate jackets.
  • Feature: 6oz Microfiber Technology
    Engineered for "Zero Drag," this ultra-lightweight fabric facilitates lightning-fast strikes and maximum mobility without the heavy drag of sweat-soaked cotton.
  • Feature: Moisture Wicking Architecture
    The synthetic diamond-weave fabric pulls sweat away from the body, keeping you cool, dry, and lighter on your feet during high-intensity rounds.
  • Feature: WKF Approved Certification
    Fully certified for use in all World Karate Federation sanctioned events, ensuring your gear meets the highest global standards for safety and design.

Sambo Store Pro-Tip

When selecting your size for the Inazuma RX, do not "size up" for growth as you might with a student Gi. These uniforms feature a specific WKF Kumite cut, which is already naturally longer in the arms and jacket tail to facilitate reach and coverage. Buying too large will result in sleeves that cover your hands, which is a violation of WKF rules. Stick to your exact height bracket for the perfect competition fit.
