Stilo ST4 & ST5 Helmet Drink System
Designed for use with Stilo ST4 and ST5 helmets. This kit, which contains all the helmet side of the Drinking System, includes a silicone rubber bite valve with anti-backflow system (YA0601), a water tube (YA0602) and a male quick release coupling (YA0603). Once plumbed into the helmet all pipes are fitted internally.
The side port (or front chin pad / vent in the case of the ST5F N) in the helmet allows easy connection to the 1.5Ltr Stilo Hydration Bag (YA0605) with its quick release connectors.
