This is a Barbarian t-shirt. While Barbarian polos are common, I don't think you see many of their t-shirts without a collar. A collarless design is easy to match with other clothes, and I think many people are looking for them. The size is M, and the approximate measurements are 50cm wide and 68cm long. It's quite thick. Made in Canada, it's an old item but in excellent condition with no particular damage. For those looking for one, please consider it.
