• Ballistic Airlight™ - 15-denier Ballistic Airlight™ hollow fiber nylon is astoundingly thin, weighing less than half of a 45-denier nylon of normal shells while offering equal strength. This strength comes from the manufacturing process where the nylon is repeatedly stretched to align the molecules, much like the tensilizing of steel, resulting in an extremely light weight, wind resistant, breathable and water resistant fabric.
