HydraPak Flux™ 1.5L Flexible Bottle - Mammoth Grey

The HydraPak Flux™ 1.5L combines the familiar shape and upright stability of a hard bottle with the packability of a flexible flask. Fill it for hiking, camping or travel, carry it comfortably by the flexible bail handle, then roll it down to pocket size when empty. The Mammoth Grey finish keeps the look understated while the 1.5-litre capacity provides useful range between refills.

Key Features

• Stands when full, packs small when empty: the structured flexible body is easy to fill and use like a bottle, then rolls down to save space.
• Lightweight design: approximately 50% lighter than a comparable hard bottle, reducing unnecessary weight in your pack.
• High-flow nozzle: the Twist-to-Drink nozzle delivers generous flow with less splash than a traditional wide-mouth opening.
• Protective dust cover: opens and closes with one hand and helps keep dirt away from both the nozzle and your hands.
• Flexible bail handle: comfortable for carrying, useful for attaching the bottle to gear and designed to secure it when rolled.
• Pack-pocket friendly: shaped to fit common backpack bottle pockets when full.
• Leakproof construction: built for dependable storage in packs and travel bags.
• Filter compatible: works with the HydraPak 42 mm Filter Cap for treating suitable backcountry water; filter sold separately.
• BPA- and PVC-free: made from durable TPU and POM for repeated outdoor use.

How to Use and Pack

Fill the Flux™ and close the cap firmly before placing it in your pack pocket. Twist the nozzle open to drink and close it after use. As the bottle empties, compress or roll the body from the base and secure it with the bail handle for compact storage.

Cleaning and Care

Rinse after each use and wash with warm water and mild soap when needed. Clean around the nozzle and dust cover carefully, particularly after flavoured drinks. Leave the bottle open until every component is completely dry, then store it unsealed in a clean, dry place.
