Naval aviators, naval flight officers, naval flight surgeons, naval aviation physiologists, and naval aircrewmen are authorized to wear G-1 seal-brown goatskin-leather flight jackets, with warfare insignia listed on a name-tag (rank optional) over the left breast pocket, either permanently stitched to the leather or attached with a Velcro hook-and-loop fastener. These jackets were previously adorned with various "mission patches," which indicate places the wearer has served. Today, patches on the G-1 are limited to a maximum of three in addition to the name-tag, i.e., a unit insignia on the right chest pocket, an aircraft type insignia on the right sleeve and an aircraft type insignia or embroidered U.S. flag on the left sleeve.
