MXXY Flexx™ Hydration System

MXXY Flexx™ is a compact and intuitive hydration system that gives users the ability to blend hydration fluids while on the go. The backpack-worn system presents users with a novel valve mechanism design and dual-reservoir that is easy to fill and clean. The adjustable dial controls flow from both reservoirs so users can fine-tune their hydration based on changing conditions or exertion levels. The design challenge of this second-generation system was to evolve the MXXY brand identity, reduce overall size, and create a unified adjustment and fluid valve system for an improved experience. Flexx is the culmination of years of partnership with the MXXY team to bring this product from ideation through manufacturing.

All-in-one control

By combining the mixing valve and dial actuator into one, and positioning the fluid blending much closer to the user’s mouth, this second-generation design is a more compact and intuitive design with greatly improved usability. This approach also reduces part count, assembly complexity, size, and weight.

Blending outdoor gear with high-tech design

This second-generation hydration system leans into its technical and precise DNA with its feature set and brand expression across materials, colors, and finishes.

A vertical attachment approach saves space

A thinner, streamlined bladder system fits better into low-profile backpacks, making it easier to use and more appropriate for athletes. We also prioritized ease of cleaning with a design that allows for turning the bladder inside out to clean hard-to-reach areas.
