Speaking about the gray color:

This specific jacket literally solved my problem of finding the right jacket for track training. Personally, the fit is a bit loose, but the comfort it provides is indescribable. Its material is very soft, proper cotton, and high-quality. It is warm and has a nice feel when you wear it. It appears quite decent and is worth its money! I highly recommend it without hesitation!

I bought it in black color and it looks faded. It is definitely not worth the 50 euros I paid.
