A safety vest with extensive anti-escape features made by EZ-ON Products of Jupiter, Florida.


This vest is made of webbing and features an adjustable, back-closure zipper. The vest provides upper body restraint, and its back closure (with included zipper lock feature) helps thwart attempts by the wearer to take it off during transport.  An adult must assist the child into the vest, ensure it is properly adjusted, seat the vest-wearing child in a vehicle seat that has an installed EZ-ON mount, and attach the vest to the mount at each mounting point. Then, a seat belt must be threaded through the vest’s routing loops.

For anchorage to the vehicle, MAXPV vest is paired with EZ-ONs MPV seat mount (100MPV), which has all attachment points to the back of the vehicle seat, making it impossible for the occupant to access them.
