Progress Jiu Jitsu Academy BJJ Gi - Black. Our durable Academy Brazilian Jiu Jitsu gi?s feature a 375GSM Pearl Weave cotton build and tear-resistant, 8 oz Ripstop Trousers. With their tough but lightweight construction, they make the perfect kimono for beginners and black belts alike and are ideal for any training gi rotation. At Progress we focus on producing the best Jiu Jitsu clothing, not the flashiest logos and designs. We recently combined our clean, minimalist design with lightweight and quick-drying material. The result was the Academy Gi ? a perfect addition to any bjj gi rotation. All of our lightweight BJJ gi?s are approved by the International Brazilian Jiu Jitsu Federation (the governing body of international BJJ competitions). With Progress, rest assured you won?t be caught scrambling for a new gi for competition because yours isn?t approved.
