Reference Manual 43 - National Park Service

Hip and Waist Length Parkas. Service or Field Uniform parkas are always worn with a badge and a name tag. Defensive equipment is worn only with the waist-length parka. The storm-flap should be buttoned to the height that the zipper is closed on both parkas. The waist length parka should be long enough to reach the belt and cover the whole shirt. ................
