Le Coq Sportif Half-zip vest, size L Mesh lining Drawstring hem Width: approx. 62cm Length: approx. 67.5cm Purchased on sale a few years ago. The tag has been removed, so the material and size are unknown, but it's probably polyester. To put it simply, it's a lightweight, slightly rustling fabric. I think you can wear it year-round. I liked it, so I wore it often. It doesn't feel very used, and I think it's in good condition, but individual perceptions may vary. Please consider purchasing if you understand that this is a used item stored at home.
