The Alpha Vest is an instructor level upgrade for both the Spartan and Goddess Vests. It is designed for extreme close-quarter combatives and repetitive, upper body striking. It adds an additional 2″ of high-density foam padding to the Spartan/Goddess Vest, along with a 2 1/2″ 360º collar, to further reduce the effects of blunt force.
The Alpha Vest is not a stand alone product. You MUST own a second generation Spartan or Goddess Vest or later in order to use the Alpha Vest.
