Templars Gear training plates are intended for military/LE/civilian use. They allow you to "train like you fight" without the risk of damaging life-saving and expensive ballistic plates.
The plates are made of extremely durable high density rubber. The plates will not crack or break when hit, dropped or hit. They are designed to replicate the weight, shape, curvature and thickness of 25x30 cm (10x12") multi-curved ballistic plates, which are more comfortable to wear than standard single-curved plates.
