Best one available for the price!!  The lining was NOT that cheap natty stuff, but a smooth soft pliable and THICK material that almost has a fur-like soft feel to it.  Inside of arms are LINED with smooth fabric so you can get your arms in/out easily - AND insulated, which is what you want if you live where it gets COLD.  The zipper seems strong and I've had no problems with it.

I'm 6'1" and 300# pounds with a tummy, and long arms  --- and the 4X was PERFECT!!  The arms were plenty long and maybe just a tad TOO long, but I'd MUCH rather that than too short!!!  No tendency to pull up when bending arms which I want.

The 3X I could get on but it was more snug than I like my winter outer-ware to be but it did contain my tummy.  The 5X which I tried, was GIANT!!!  Way too big for me, too LONG for me including arms - but great for guys say, 6'3 or more with a tall torso" and maybe 350# or so just for a loose reference for you prospective buyers.

Or the 5X for 6 foot ish guys that are REALLY chubby, but expect it to be too long in the torso and the arms too long too if you are just trying to get something your tummy can fit in.  But hard as that is to find in an AFFORDABLE BIG zippered hoodie for the big eaters, you'll still be happy given the low price of these.

 The Big Guy stores online are waaaaaaay too high on these, and I bet these are the same or better than theirs.  They did not pay me for this.  I'm just thrilled I found something so nice for a BIG guy - and you other big guys know what I'm talking about.  It's hard to dress us with decent winter wear.

Seems almost all big man stuff runs small when you get it home, but NOT THESE!
