Alpha Industries Bomber Jacket MA-1 Flight NASA Please check measurements, there is no size tag because jacket is reversible. Measures flat approximately: 21" armpit to armpit 20" sleeve 24" top to bottom seam I bought this at NASA and loved it. The model pic shows a red ribbon on zipper which I no longer have. So fun to wear this, looks very official I am a Small in most things so am tagging as a Small. Very nice used condition. No rips, stains or tears.
