Going by SM's website, this covers chest sizes from 44 to 46. That includes making the parka a little oversized to accommodate wearing a tunic underneath. The actual chest measurement is 56 all around. I feel like it has the perfect amount of aging, that being some discoloring to the white side, including some equipment stains, and just a touch of fading on the camo side.
It looks super-authentic and event ready straight out of the box.
