All Tac-Trainer™ products are made in the US and are field tested. Only top quality materials are used in the construction. The foundation of all Tac-Trainer™ products is the inner core. This inner core is made up of various impact resistant nylons and incorporates a "Tension Armature" design that can be configured to adjust the rigidness of the training tool. The striking area utilizes a blend of high density polyethylene foams to ensure safe use. Another unique feature is the "Ballistic Nylon" shell that covers the striking area. Ballistic nylon is very durable and water repellent. This allows any foreign material such as sweat or dirt to be easily wiped off.
