Our E-Vest is a magnetically operated, remotely controlled CD3 that uses the same technology as our flagship product the G.L.O.V.E. The E-Vest comes in two adjustable sizes. It is effective for prisoner transport and brings subjects into compliance during acts of aggression or attempted escape. Each E-Vest comes with two magnetic keys and two remote controls that have a range of over 150 yards. This is a proven, discrete, effective and humane solution to control subjects, especially when time is of the essence.
