The climate confort windscreen contains an additional filter to block infrared light and create a cooler environment inside. Though practically transparent, you can notice this film from the cut-out areas around the sun visor, which helps RFID devices to be installed (toll gate devices etc...) because the film may block also the emisions of these signals to and form these devices. Definitely a must have option in hot climates or where the sun is very bright. As a matter of fact anywhere in South Europe, Middle East and Africa it comes as part of the "hot cliamte" package or "tropical countries" option. Also, it comes as std with the green ribon on top.
