WW2 Pilot's Jacket?

[27Division18]

Is this a WW2 pilot's jacket of some type? I cannot see a tag inside anywhere and it is a very small size.

It has the design elements of a B-10 introduced and in use for a several months in 1944. There are a lot of civilian made ones though. Closer examination of the zipper, pockets, etc and evidence of whether a tag was ever mounted in the collar would help in making a determination on whether this was government contract or not (with a missing label). Good luck.

Pull the sleeves inside out and see if there is camo HBT material sewn at the cuff.

The B10 had square patch pockets, the B15 had slash internal pockets - but on GI B15s there is a snap closure for the pockets.  I think its a commercially available (possibly post war) private purchase coat.

Austin is absolutely right on the pockets I didn’t catch that .
