How are CoolFlo windshields different from other shields on the market?  To answer this, let’s look at what creates the problem.  An open, roll-caged vehicle lets air flow freely while in motion.  Put a windshield on the vehicle and the flow of air is changed - a low pressure zone is created behind the windshield.  Ever ride in a jeep or convertible car and wonder why your hair blows forward toward the front or windshield?  It is because of this low pressure.  Automakers have addressed the issue by adding spoilers to roof racks and rear windows to create an air curtain.  This works at highway speeds, but the problem still exists at lower trail speeds. It is this low pressure zone that draws the dust into the cab.

By simply removing the lower section of the windshield, air is redirected by special foils downward to the floor and backward into the cab, effectively breaking the low pressure zone and forcing trapped engine heat out of the vehicle. The upper portion of the CoolFlo Windshield stays in place for much needed eye and face protection. What if it’s too cold to ride without a full windshield?  Leave the bottom part on and take it off later if you need to.  Others have tried to fix the dust and heat problem by making half or three-quarter windshields. This only reduces the low-pressure zone; it does not break it.  And half windshields do not provide adequate eye protection.  So, with a half windshield you have no upper protection, only slightly less dust and the cool air is blown over your head without providing any relief.
