Ideal for walking, running, hiking, biking, or when outside for hours, the Convertube connects to almost any bottle and lets you drink without removing it from your backpack. 

Convertube Set-up

The kit contains four adaptors for four different bottle-neck sizes and threadings, and the standard 90cm drinking tube with Helix bite valve, protected thanks to the Dirt Shield valve protector from sand and mud.

How to use

Convert a bottle to a hydration system in three easy steps: after determining the size of the bottle’s opening, thread the tubing through the adaptor’s hole, and screw on the appropriate adaptor tightly so no water leaks. Access fluids through the Helix valve.
All adaptors, tube, and valve can be cleaned with warm, soapy water and reused.
