Source Convertube

Drinking hands-free and anytime from the bottle is possible with the Convertube from Source! The drinking system kit includes a standard adapter with internal threads (e.g., for PET bottles, 26 mm) and comes with three additional adapters, a hose with the Helix Bite Valve, and a Dirt Shield protective cap. This kit fits various closure sizes. With this clever attachment system, there's no need to take the water bottle out of the backpack anymore! Additional adapters: 26 mm adapter (external thread), 30 mm adapter, 63 mm adapter.
