Thank you for your interest in this item. This is an icebreaker half-zip base layer. It has been stored at home, so I'm offering it to someone who can use it. The color is a navy-like shade. The size label has faded, but it's a size S. I believe it corresponds to a Japanese size M. Size: M There is some wear on the neck tag, and there are also some snags around the stomach and back, so I'm offering it at a reduced price. Please purchase if you understand that this is a used item.
