The Authentic is the ONLY commercially produced peacoat on the market today that accurately reproduces the look, feel, warmth and durability of the U.S. Navy issue peacoat. Don't be fooled by cheap imitations, sold at department and specialty stores, that claim to be "Official" or "Specification" peacoats.The size chart is provided as a guide to help you in determining which size peacoat to buy. Generally speaking peacoats run tight across the chest and back. Our recommendation is that you upsize one size from what you are accustomed to wearing (i.e. if you usually wear a 38 regular suit coat, or your chest measures 38 inches, then you should order a 40 regular peacoat.) This formula will also allow for extra clothing (i.e. a heavy sweater, etc.)
