With the Vest connector HV any jacket can be upgraded to greater visibility. It is designed to wear over all jackets in a subtle and stylish way. The vest can be fixed to the outer shell of almost all the new style jackets with Velcro loops. Thanks to the mesh fabric it ventilates well and it won't flap or bubble out. For a snug fit the vest can be adjusted on the sides. The neon yellow EN-471 certified fabric combined with the 3M ScotchliteTM reflection stripes dramatically increase riders' visibility. A small upgrade with great benefits.
