A clever drinking system for use with standard PET bottles (neck diameter 28 and 30 mm). In a flash you can covert your bottle in to a complete and inexpensive drinking system. The straw length can be adjusted to the depth of the bottle and the bite valve is easy to suck through. A one-way valve in the stopper provides the air flow.
Slightly self-glowing water bottle with large neck. Manufactured from the new BPA free Tritan(TM) Copolyester that is utterly taste neutral. Absolutely proof, easy to clean and virtually indestructible. Can be found easily in the dark, e.g. in the tent.
Flexible water tank with integrated hydration tube made of atoxic plastic that does not alter water taste. Easy refilling, cleaning and draining thanks to its wide opening at the top side. Ideal for hiking, cycling and bike travelling.
The Helix Valve provides full water flow with just a soft bite. The cylindrical shape requires no special mouth orientation. The retreat spring sealing mechanism is leakproof even after prolonged use and under pressure. The kit includes Helix Valve with dirt shield for protection of the valve from dust and dirt.
