This is a light-weight tailored jacket Z made of recycled polyester fabric from GU. I bought it this season, but I haven't had many opportunities to wear it. It's dark gray, and thin, so it's good for layering when there's a big temperature difference, and it's convenient for adjusting the temperature depending on the inner layer. I also felt that it doesn't wrinkle easily. It's a size S, but it's not overly oversized, and the fit is nice without being too tight. I'm disappointed that I couldn't make good use of it myself. It's a used item, so it may not be suitable for those who are sensitive, but it seems like you can wear it comfortably overall. No stains, tears, or odors...
