Thank you for viewing. This is a Phiten T-shirt. The size is L. It's an old model, so it's equivalent to the current model's O size. The fabric feels slightly thicker than the current model. It's a set of two shirts: one with a gold logo on red fabric, and one with a red logo on white fabric. There is some wear and slight staining, so please refrain from purchasing if you are sensitive to these issues. Please understand that these are used items. I am selling these as I declutter. If anyone fits the size, please take them.
