Progress Jiu Jitsu M6 BJJ Gi Mark 5 - Black. Our durable M6 Brazilian Jiu Jitsu gi features a 450GSM cotton build Gi Jacket with a vulcanized rubber lapel and tear-resistant, 10 oz Cotton Twill Trousers. This is our most legendary gi yet, with competitors winning Blackbelt World Championships while wearing it. At Progress we focus on producing the best Jiu Jitsu clothing and the Mark 5 takes another step forward in our product progression. With updated high density embroideries on each arm and a flash red inner trim inside the jacket; this is our proudest creation to date. Our mens 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.
