Officers love these! Design driven by research, a spine-safe posture and low-profile appearance make these unique Zero-G plates a have-to-have item for any uniformed officer. The Zero-G's distribute the load of the duty belt onto your hips and legs, where the body's natural weight-carrying ability resides - not your back. The way the plates join with your duty belt maintains an almost invisible appearance, and does not interfere with the duty belt or its utility at all. They are made from non-reflective carbon fiber hi-tech construction, overmolded for comfort, and they are durable. The inner face of the plates match the velcro of a trouser belt. Many Officers report they can feel the difference in minutes after adding these to the duty belt.
