The Stearns V1 Life Jacket features the revolutionary V-Flex design: a deep vertical "V" sculpted into the back of the vest flexes with your every move, giving you perfect fit, excellent range of motion and outstanding response to your twisting or reaching movements. The innovative ride-up tabs let you easily reposition the vest while wearing it to avoid ride-up. 1.5" webbing provides a secure closure. The V1 PFD is made of durable, lightweight, fast-drying hydroprene over lightweight PVC foam. A convenient dry ring is built in. This Type III personal flotation device is Coast Guard approved.
