Multicurved Training Plates form Templars Gear are designed for Military/LE/Civilian use. They allow to "train like you fight" without risk of damaging your life-saving and expensive ballistic plates. 
Plates are made of extremely durable high density rubber, with steel core (only 2.5kg version) for added weight. Plates won’t crack or break when hit, dropped or impacted. They are designed to replicate the weight, shape, curvature and thickness of 25x30cm(10x12”) multicurved ballistic plates which are more comfortable to wear than standard single curve plates. Two weight standards are available - Standard 2.5kg/5.5lbs (25mm/1” thick) and Lightweight 1.5kg/3.3lbs(20mm/0.78” thick), for user preference.
