HydraPak Flux 1L – Ultra-Light Collapsible Water Bottle

HydraPak Flux 1L combines the convenience of a traditional hard bottle with the packability of a soft flask. When filled, it maintains its shape and stands upright like a hard bottle. Once empty, it compresses and rolls down to pocket size, saving valuable space in your pack.

According to HydraPak, the Flux cuts weight by approximately 50% compared with a hard bottle. The 1-litre version weighs just 102 g, making it an excellent choice for hiking and travel where reducing pack weight matters.

Roll-to-Pack Design

When empty, the flexible bottle can be compressed and rolled into a compact package. The flexible bail handle provides comfortable carrying, allows quick attachment to your pack and can be used to secure the bottle when rolled up.

High-Flow Twist-to-Drink Nozzle

The Twist-to-Drink high-flow nozzle provides increased flow with less splash compared with a traditional wide-mouth bottle, making hydration quick and convenient while on the move.

Protective Dust Cover

The integrated Dust Cover helps keep dust and dirt away from the drinking nozzle. It opens and closes quickly with one hand and helps prevent direct contact between the nozzle and dirty hands or surfaces.

42 mm Filter Compatible

The Flux is compatible with most 42 mm water filters, providing a versatile solution for backcountry water treatment. HydraPak specifically lists compatibility with the HydraPak Filter Cap and Katadyn BeFree.

Durable TPU Construction

The Flux uses TPU and POM materials and is designed to provide a lightweight yet durable hydration solution. Its flexible profile fits conveniently into pack pockets when full and packs down small when empty.
