Introducing the Unknown Koi Gi, our cutting-edge addition to the BJJ world. Merging the latest advancements in gi technology, this remarkable release redefines comfort and performance. With an emphasis on superior ventilation and durability, the Koi Gi sets a new standard in gi design. True to the ethos of Progress gis, the Koi is meticulously crafted from premium materials, showcasing the unmistakable Progress Jiu Jitsu aesthetic that practitioners know and love. Notably, we've elevated the stitching technique on this gi, bolstering embroideries for heightened strength and intricate detailing. Each back panel embroidery for example, takes 1 full day to complete. Unveiling the Unknown Koi Gi is an experience in itself – as the double zip ripstop bag opens, a burst of rich colours and meticulous features greets you, reflecting the fusion of innovation and artistry that defines this exceptional Jiu Jitsu Gi.
