This is an Oregon Project T-shirt. A valuable early model with a back print and mesh material. Size: Japanese M. I wore it a few times for running, but it's still in good condition. There are no tears or noticeable stains. The print is also intact. I don't think the Oregon Project T-shirts will be re-released.
