Our world famous Maxx-Dri Vest for body armor cooling and ventilation was created by co-founder Suresh Madhavan. As a police officer committed to wearing body armor, he was determined to find a solution to soaking in sweat, smelling, and being distracted by skin irritations and even infections. He figured out that, 1) his base-layer shirt needed to be breathable, not just moisture wicking, and 2) to make it breathable, he needed a layer of space between his shirt and body armor that allowed body heat and moisture to escape and air to flow in. So he created a lightweight vest made out of a special mesh material—the “Maxx-Dri” material—to go between his body and his armor. (Also see our Maxx-Dri Backpack Airflow Spacer.) Maxx-Dri vest worked brilliantly, a true game changer, as attested to by a quarter-million customers over the past 10 years.
