Thank you for viewing. This is a long-sleeved shirt (with a collar) from THE NORTH FACE. I bought it for mountain climbing, but it was a little too small for me, so I'm putting it up for sale. *I usually wear a size M. I think this item will be useful as a mid-layer in the coming season. (It's a thin fabric. See photo 5) The color is easy to coordinate. - Model number: NTW11829 - Size: S - Color: Navy I'd like to sell it to someone who will wear it. Thank you.
