ST4 ST5 Helmet Bite Valve Hydration Pack - Blue
The Stilo drink system helmet kit includes a male coupling, tube, and rubber bite valve. The coupling assembly is designed to allow the driver a quick evacuation so that in case of emergency, by just a slight tug, the coupling slips off--releasing the driver. All pipes are fitted to the helmet internally. The kits are designed for use with specific Stilo helmet series.
