Longer-lasting gi for jiu-jitsu 19th May 2021 The gi is the traditional uniform for jiu-jitsu, a popular martial art in many countries, including Brazil. It is made from a thick fabric, and the wearer tends to sweat heavily when performing. A typical gi can take as long as two days to dry after being in the laundry, leading many users to purchase two or three so they can be wearing one while the other is being washed and dried. Brazilian brand Kvra is the first company in the world to offer jiu-jitsu gis treated with Polygiene Stays Fresh technology and believes it will enable athletes to use the same uniform multiple times.
