Airsoftjunkiez got something to make you cool whilst still looking tacticol under the summer heat with the Body Armor Vent. This is what its makers say about this product... "The BODY ARMOR VENT™? was designed to solve a problem. Invented by a retired Sheriff, who was injured in the line of duty, he asked himself during physical therapy, 'what was the worst thing about being on patrol?' The answer: the heat and sweat build up behind his body armor, especially in the heat of summer. With that thought the plans for BODY ARMOR VENT™? began and the journey that led us to where we are today. BODY ARMOR VENT™? is sold worldwide and used everyday by thousands of government and private sector military and law enforcement individuals wearing body armor. Our BAV helps provide maximum comfort while you’re wearing your body armor, summer or winter."
