Immediate purchase OK. Ships within 24 hours. This is a utility shirt, possibly military issue or a supply item. There are no tags except at the base of the collar, so I couldn't investigate further. However, it's 100% cotton and olive green, giving it a great vibe. Depending on your build, it can be worn as a shirt or as a light outer layer, and will be useful in the coming seasons. Personally, I think it's convenient to wear over a hoodie or a denim jacket. Of course, it's also useful in the summer to wear over a t-shirt for sun protection. We primarily list items that are clean with minimal damage such as stains and no tears, not only for airsoft and military enthusiasts, but also for those who want to incorporate vintage and military styles into their fashion. It's a versatile shirt, so please consider it.
