Having a dilemma as to what size I should look for in an ANJ-4 jacket. I previously owned a size 44 Eastman Irvin which fit well but I didn't care for the bulk of the shoulders/arms as a daily winter jacket and found it tough to drive in. I currently have an Eastman D1 that I swore I ordered as a Large but the tag says XLarge. It fits nicely. Snug but not tight with full movement. I am 5' 11. Relaxed my chest measures 41" and with a deep breath it is 42 1/4. My waist is 41" and at my belly button it is 42 1/2" I weigh 200 pounds. I was looking to buy an Aero ANJ-4 but they recommended I go for a size 42 when given these numbers which just seems wrong to me. Opinions?
