The adidas BJJ Contest Gi/Kimono features 450 gram "Adi-weave" 100% cotton fabric. This reduces shrinkage after the first few washes to an acceptable degree. The jacket is slightly tailored so as to reduce unnecessary fabric around the mid section. The jacket has our classic 3 stripes down the shoulder, and directly embroidered from the hip to mid thigh. Perfect for every day training or goin' hard in competition. IBJJF Approved!
