STILO ST5 AND ST4 HELMET DRINKING SYSTEM
Designed for use with Stilo ST4 and ST5 helmets with Drinking System preparation. 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 Hydration Bag with its quick release connectors.
