Initially, nothing other than an open mind and maybe, tracksuit bottoms and a T Shirt. If you fall in love with the art and wish to progress more you will need to purchase a Kimono or 'GI' as they are more commonly known. It is the standard uniform that most of us start from when undertaking a journey to learn Jiu Jitsu.
The beauty of training No GI Jiu Jitsu is you won't need a Kimono and can train in just basic shorts and a T Shirt. We use our bodies as our training tools. We simply recommend that you refrain from wearing watches, earrings, rings, bracelets as it is a full contact sport.
