Fanny Pack Holster The Passport Fanny Pack Holster is available in two sizes - small and large - and in two colors - black and light gray. The gray model, particularly in the small size, is especially popular with women, perhaps because the gray model is less easily recognized as a holster. The gun pouch, located behind the fanny pack itself, seals with Velcro and a snap. Additional zippered pockets on the front provide easy access to spare magazines and other small items. The large size has a belt clip concealed on the back which helps to relieve stress on the lower back when carrying a full-size auto, and helps to avoid the weighted-down look. Note: In normal use, the gun simply lays at the ready inside the gun pouch located behind the fanny pack. The inside of the gun pouch will, however, accept a Passport Inside-the-Pants Holster with thumb-break snap if additional security is required. (This option is generally not needed except by joggers and some law-enforcement personnel.)
