A-2 Deck Jacket Fit Question

[Rumor_Control]

Thinking about picking up a Buzz Rickson repro of this jacket.

I'm 5 11 and 164. Chest measure 38". Am I good for a medium or is going to be snug if I'm layering a sweatshirt underneath? I've worn a MA-1 jacket in a size 40 and it's decent fit, but it's pretty roomy / sleeves are maybe a touch long.

I'm 6.3 and 220 lbs and the "L" suits me fine with still space for layering so the "M" should do the job for you ...
