The Shomer-Tec Sap Cap may look like a regular baseball cap, but it’s really a self-defense “weapon” that you happen to wear on your head. The fact that it looks exactly like an ordinary cap means attention won’t be drawn to it. Hidden in the back is a special pocket that holds a pouch of metallic micro-spheres that have the density of lead without being toxic. When you need to use the cap for self-defense, the bill becomes a handle of a non-lethal blackjack style weapon. The Sap Cap is one size fits all, is only available in Black and is priced at $29.
