PLEASE NOTE: While this jacket is compatible with our Tech-Air 5 Vest system, if you are looking for complete integration (zipping the Tech-Air vest directly into the jacket and hooking the Tech-Air vest up via quick connect cable to have the vest transmit information to the LED panel on the jackets sleeve) you will need to purchase the Tech-Air race system as the Tech-Air 5 vest is a standalone vest with the LED panel directly on the vest itself and will not zip into the jacket or plug into the jacket via quick connect cable.
