Blade-Tech Instructor's Belt The Blade-Tech Instructor's Nylon Gun Belt is made up of two layers of tough nylon webbing with a polyethylene reinforcement built into the tactical belt. This allows for a full range of movement with enough rigidity to hold up even the heaviest of setups. The AustriAlpin COBRA® Buckle quickly clicks into place and utilizes a staggered head sizing so you can run the small buckle end through your belt loops without having to remove the COBRA® Buckle. Made in the United States.* To find size, measure your waist with a fabric tape measure. In most cases, you can add 2-4 inches to your pants size to get the proper belt fitment.
