New! CE Certified Airbag Vest Shock absorbing pads are incorporated in the chest area, and the airbag and shock absorbing pads provide excellent shock absorbing performance. The MLV3-H offers a greater range of protection due to the large volume of the airbag. Once activated, the buttons automatically open by air pressure and the airbag inflates to a large size. The harness-style design allows for a wide range of compatible sizes and the waist belt allows for size adjustment. It can be worn all year round, over both spring/summer and winter jackets.
