I believe this is a sample item. It's packed with various logos like skulls, crosses, Los Angeles Angels, and more. I bought it on impulse because of the design. The tag says M, but it's an overseas size, and I, who usually wear LL, can wear it as an outer layer. The measurements when laid flat are approximately 61 cm chest width under the arms and 70 cm length. Short lengths seem to be in fashion lately. Of course, there are pockets on both sides. It's not a "bajack" (likely a typo for "baggy" or "oversized" in a casual sense, or perhaps a specific brand/style name not widely known).
