Full Battle Dress is used to describe the equipment and clothing a warrior wears when going into combat. It comprises all the gear they need to fight the battle. The Lenwood Full Battle Dress (FBD) is designed to be just that. An appendix inside the waistband (AIWB), it is designed to house your pistol and a spare magazine. Having the two pieces of equipment built into one solid piece of gear eliminates the possibility of finding yourself without a backup magazine.
