From KA-BAR Knives, the Tactical Defense Institute (TDI) Fanny Pack is 100 percent polyester and acts as a self defense carry-all that fits up to a full-size firearm without imprinting. Additionally, there are multiple pockets, loops and straps for carrying pens, extra magazines, a cell phone, badge, keys and flashlights. The TDI with black metal belt clip attaches securely to the back of the pouch on one of two loops for concealed carry.
