Mustang Survival's outer shell is made of a superior quality 420-Denier type 66 high tenacity nylon yarn. This means improved ultra violet protection and longer product life. Mustang's nylon outer shell greatly exceeds US Coast Guard's UV (weathering) standard and easily passes the Canadian Coast Guard's demanding 300 hour testing.

Many Mustang products are interlined with exclusive AirSoft closed cell foam. Air Soft provides buoyancy and hypothermia protection in-water and reliable insulation on deck. The AirSoft interliner is specially bonded around all seams to form an effective protective barrier against the elements.
