The HydraPak Flux represents a new approach to portable bottle design, combining the best features of both rigid bottles and soft flasks. Its standout advantage is a shape that can stand upright securely like a hard bottle, while still being compressible for easier packing and storage. It is also engineered to be more than 50% lighter than a traditional hard bottle. The cap features a twist drinking nozzle with a dust cover, and the bottle is finished with a durable carry handle for added portability.

Features & Technology
FLEXIBLE BAIL HANDLE
A highly flexible carry handle designed to serve three functions: making the bottle easier to carry, allowing it to be attached to a backpack, and acting as a strap when the bottle is folded for storage.
FITS IN PACK POCKET
When packed down, the bottle fits neatly into standard backpack side pockets for convenient storage and access.
LIGHTWEIGHT & COMPACT
More than 50% lighter than traditional water bottles, and compressible down to a compact size when empty—small enough to save valuable pack space while reducing carried weight.
HIGH FLOW NOZZLE
The twist drinking nozzle is designed to provide better water flow and directional control than a standard bottle opening, helping reduce spills and unnecessary water waste.
DUST COVER
To help keep the drinking nozzle clean and ready for use, the HydraPak FLUX includes an easy-to-use dust cover that helps prevent contamination.
