This is a long-sleeved shirt from Aizu Frontier. I bought it because it looked cool on a mannequin at a workwear store, but I mostly wear Toraichi, so I've only tried it on once. The Aizu Frontier logo on the back really stands out. It's stretchy and easy to wear. I usually wear a size M, but Aizu Frontier tends to run a bit small, so a size L is just right for me. I'm 165cm tall and weigh 58kg. Please refrain from purchasing if you are overly concerned about details. Workwear Workman Craftsman
