HydraPak® HydraFlex™ Performance hydration tube

The flexible HydraPak HydraFlex tube is lightweight and compatible with HydraPak hydration bags, especially the Contour and Contour Lumbar models. It is adapted to use in the field and does not make knots on it.

Fresh water all day long

The HydraFlex tube is made of tasteless and odorless thermoplastic polyurethane (TPU), so the water you drink from it will have no taste or aftertaste. Fresh water with a neutral taste may paradoxically taste the best. And you will be motivated to stay hydrated throughout the day on the go.

Self-sealing plug-in valve

The innovative and lightweight Comet valve seals itself after each sip and does not leak. It can be opened and closed with one hand to prevent liquid leakage when the tube or hydration bag is not in use.

Flexible without knotting

The drinking tube has been designed with the ideal hardness for easy routing through the hydration system of the backpack. The tubing is flexible and does not form knots that could potentially disturb the flow of water when drinking.

Material that does no harm

The tube does not contain harmful substances such as bisphenol A (BPA) and PVC. At the same time, thermoplastic polyurethane enables use even in extreme temperatures. While on the one hand the drinking tube can be frozen, on the other hand it is harmless to health up to 60 degrees Celsius.

Universal screw connection

The HydraPak HydraFlex connects to the hydration pack with a ¼ inch universal fitting (connector). At the same time, the tube uses the Plug-N-Play connection system, so connecting it to and disconnecting from the bag is a matter of moments.
