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 white logo on blue fabric, and one with a white logo on light blue fabric. The light blue one has some stains. Please refrain from purchasing if you are sensitive to this. Please understand that these are used items. I'm selling these as I'm decluttering. If anyone fits the size, please take them.
