The original U.S. Air Force  (USAF) Flyers CWU-9/P quilted liner jacket is a lightweight insulated piece originally designed as a liner for military flight jackets. Its clean, functional design has made it a popular standalone jacket.

Made from durable nylon with polyester filling, it features a classic quilted “onion” pattern that provides light warmth without bulk. Details include a front zipper with snap buttons, ribbed collar and cuffs, and practical pockets.

With its relaxed, slightly boxy fit and authentic military heritage, the CWU-9/P is a versatile piece ideal for everyday wear or layering.

Production discontinued in the 1990s.
