Being patterned after a navy G1 but with an A2 front and sensical side pockets it is an official US Gov. jacket. and I'm glad I jumped on it as 48 is actually a 46 following Navy standards. It was cheap and in excellent shape requiring only some stitching on the back side of one cuff. I'm going to be keeping my eye on ol' Rare Gear as their prices are outstanding. Kinda like finding those military treasures in thrift stores in NYC back in the 80's.
