HanitaTek Sigma 50% VLT Auto Nano Window Film

Sigma™ is a 1.5-mil non-metal car window tinting film in a "natural black" color. It will not interfere with any electronic signals - GPS, iPhone, tire pressure monitors, etc., will all function perfectly. Using nano-technology means that the energy performance of Sigma is better than dyed films. In fact, Sigma 36 rejects as much heat as many limo tint films keeping a car cool without breaking tint laws in most states.
