Everything that can be done without the Kimono can be done with it, making it a more complex game. Additionally, taking away the Kimono allows physical attributes such as size, strength and slipperiness to come to play with greater effect due to the lack of levers and friction. Working with the Kimono is generally considered more of a ‘thinking man’s’ game. Not that no-kimono isn’t, it’s just that the Kimono removes many physical advantages and ads more techniques. For now, you should view your Kimono as a set of training wheels. As you develop a higher level of proficiency, you will learn to perform Jiu-jitsu techniques both with and without a Kimono. For now, the Kimono will add a level of sophistication to your game that will result in you as a student becoming a more advanced and technical fighter.
