This seems to be a replacement for the Single Zippered Breast Pocket Beige Jacket, which had been torn, bloodstained, stabbed, and burnt, before wardrobe figured out that maybe it couldn’t be recovered anymore. This coat has no breast pockets, only lower zippered front pockets. It both zippers and snaps, and seems to be a beige version of another one of Sam’s Dark Coat which was also introduced in S3.
