CarharttMen's Midweight Hooded Sweatshirt, Navy, S

Did anyone notice and poofing on the front of the sweatshirt right at the zipper in between the pockets after wearing/washing a few times?

I have a nice size gut and was wondering should i get a 4xl im 5"11 and 285 lbs

What is the length?

Is it cotton or not?? One place says 100 percent cotton. In another it says 50/50 cotton/polyester??
