Hydrapak Flux 1 L Ultra-Light Reusable Bottle

Flexible bottles get an upgrade. The Flux is shaped like a hard bottle, compresses like a soft flask, and cuts weight by 60%. Topped with a spill-proof twist cap for grab-and-go hydration, plus a bail handle to keep hydration secure in your hand or on your pack. Finish your drink, and this bottle packs down to earn its space in your pack. With the Flux, innovation fuels performance.

Providing a sustainable drinking alternative is the Hydrapak Flux Bottle. Constructed using dual-layer film laminate and RF-welded soft walls, the Hydrapak Flux Ultra-Light Bottle features added structure and good grip without compromising on compactness. At only 77g, it packs down smaller than a deck of cards making it the perfect thru-hiking essential. A unique drink-through cap with a spill-proof valve allows for easy drinking and no leak usage. The Flux attaches to most 42mm threaded water filters so that you can use it as your backcountry squeeze bag or drink directly through it.
