Coolcop attaches to a vehicle's air conditioning and directs cold air behind an officer's vest where they need it most. The Coolcop dashboard attachment just snaps into the air conditioning vent in seconds. The soft vinyl vest attachment then fits comfortably between your vest and undershirt. Cool air is then delivered under a vest to keep officers cool, dry and comfortable. Coolcop comes with 6 inches of crush-proof flex hose and installs in the most common police vehicles.
