A sweet rashguard in limited edition that makes you stand out on the mats. Sankaku means Triangle in Japanese, and has always been a strong symbol within the jiu jitsu community. The Penrose triangle has been called ”impossibility in its purest form”. An unsolvable enigma, just like Jiu Jitsu. That’s why we call it ”the impossible art”.
