5.11 Tactical has encased Zoombang—the world's most advanced energy-dissipating material—in a heavy-duty, abrasion-resistant, urethane envelope designed to fit comfortably between you and your armor. At rest, ZB-7 is soft and conforms easily to the body. But under shear force from blunt-trauma impact, vibration, or g-force side loads, it temporarily transforms to a solid to dissipate energy. Grooves built into the pad help improve airflow and allow its semi-liquid nature to conform to your body.
