Why the use for tape ?

Ain’t fashion; ain’t show off… is just for the simple fact, thru the years, your joints starting to swollen, and with a little piece, you can protect them and in some cases, serve as a cushion for the fingers. For the extreme cases, the mat burn, common for any beginner, protects them. When I started Jiujitsu, the mats were made by heavy canvas, same as they use for boats in the 80’s. Nowadays, for sure technology involve in bjj but, is better feel worry than sorry and be out of Jiujitsu.
