It has the gas flap. Size S tag. This one seems bigger than most size smalls - probably because it looks like the darts were taken out to accommodate a larger size. You can see where the stitching was and there are tiny holes in that area. It is in OK condition. Wearable, but with flaws. One of the pocket flaps is torn under the button hole. Some general overall wear and some staining. The most noticeable staining is on the sleeves and above one pocket (although there are other stains in other places). No attempt has been made to launder it. Some pulls in the material.
