Armored Combat:Equipment standards - Armor - Body shoulder groin

Body, shoulder, and groin armor

1. Your kidney area and your floating ribs must be covered by a minimum of 11/64 inch (4.4 mm) or 11 oz thick stiff leather worn over 1/4 inch (6 mm) of closed-cell foam or equivalent padding, or armor that provides equivalent protection.
2. Body armor to protect all of your ribs is strongly recommended.
3. If you have testicles, they must be protected by groin protection equivalent to that provided by an athletic cup, secured by straps, or worn in a supporter or garment designed to hold the protection in place.
4. Non-Newtonian padding such as Zoombang only counts as equivalent padding for meeting armor requirements.
