BODY ARMOR VENT’s Backpack Retro Fit Kit, available in four sizes, is designed to fit all backpacks.
The Backpack Retro Fit Kit panel featuring our patent-pending evaporation and ventilation technology; EVAP is the continuous air flow between your torso and your pack. Air flow around and through the panel is driven as the hot air expands and your own breathing provides the air flow which then produces evaporative cooling. Air moving over moisture, just like an AC!
BODY ARMOR VENT’s inflated, vertical air channels force air flow upwards and also through horizontal vent holes to enable true evaporation of sweat from between your back and the pack. This keeps your body’s temperature down in the summer and your body much drier and warmer in the winter.
*All Retro Fit Kits are made with “loop” fabric on the back (reverse) side that attaches to our exclusive, SUPER GRIP “hook tape”.
**Backpack and other items displayed in product images are not included. See specific Retro Fit Backpack Kit sizes for package contents.
