Powerade PowerPak

The Powerade PowerPak is a unique self pressurising hydration pack that allows you when in need of a drink to do so without any fuss.

There’s no need to pump before you set off, just run, skip, jump or walk and the Powerpak does it all for you, by using the movement of the user to pressurise the water reservoir, allowing a constant stream of water to flow from the drinking tube. Ideal for drinking, cleaning, and sharing with ohers.
