Chef WorksMen's Gramercy Denim Coat

I does wear a medium in chefwork coat should I get a medium in the denim coat

Any thoughts on durability? Color fade, material integrity, shrinkage after laundering etc...?

Will this keep me hot in the kitchen?

I usually wear Lg but only medium was available. It's not tight, barely restricive. I'm hoping it wont, but will it shrink???
