New without tags. Light gray color. Unbranded. Front panels are lined. 4 zippered pockets & 2 flap pockets on the chest. No fabric content or care tag. Fabric has a soft feel. My guess is that it is nylon or a cotton/polyester blend. The size tag says 4XL. It is MUCH smaller. I am guessing it is a 2XL. Please carefully check measurements below to ensure fit.

Approximate Measurements:
