MXXY Flexx Hydration System




What we think

The keystone feature of the Mxxy line up is their Flexx Hydration System.

The Flexx Hydration System with a Mix Dial allows you to plan your hydration and fueling seamlessly with a unique dual reservoir pack. That means you can carry both water AND mix in your pack and change how much of each you receive at any moment. Rad!

It's not just for the Mxxy packs, either. You can fit this system into just about any pack on the market...which can be great for keeping your current favorite pack while upgrading what it can do!

Adjust your mix on the fly as the conditions or your exertion levels change for perfectly dialed hydration and fueling.
