The Ridgeback M4+ is a multi‑curve, standalone ballistic plate engineered to deliver high threat protection with improved wearability. The plate measures 9.85 inches by 11.8 inches with a 1.06‑inch profile and weighs approximately 7.8 pounds, balancing coverage area with reduced carrying mass. Construction integrates a ceramic strike face and full‑coverage UHMWPE backing designed to defeat multiple impacts, including .30 caliber armor‑piercing projectiles at 2,800 feet per second under NIJ 0101.06 testing protocols. Ceramic tiling extends across the full face of the plate to maximize strike surface effectiveness.

An integrated anti‑spall sleeve incorporates four layers of front‑facing aramid fiber to mitigate fragmentation, paired with a rear‑facing trauma pad to reduce blunt force transmission. The multi‑curve geometry promotes a natural fit against the torso, improving weight distribution, comfort, and mobility during extended wear. Drop testing on concrete surfaces has demonstrated retained ballistic performance after impact, reinforcing durability for operational environments where reliability under stress is critical.
