Hydrapak Flux 1 Litres (Tahoe Blue)

Save pack space without giving up the familiar feel of drinking from a bottle. The HydraPak Flux™ Tahoe Blue has a structured flexible body that stands upright when full, then rolls down into a compact bundle once empty.

The 1L version is sized for everyday adventures and day hikes, while the 1.5L option gives you extra range for longer outings and campsites. Both use a twist-to-drink high-flow nozzle, protective dust cover and flexible bail handle for straightforward hydration on the move.

Key features

• Hybrid bottle design: combines the stable shape of a rigid bottle with the packability of a soft flask.
• Roll-to-pack storage: compresses after use, freeing space inside a backpack or travel bag.
• Low carried weight: designed to weigh about half as much as a comparable hard bottle.
• Twist-to-drink nozzle: delivers a high, controlled flow with less splashing than an open wide-mouth bottle.
• Nozzle dust cover: helps protect the drinking surface from trail dust and dirty hands.
• Flexible bail handle: comfortable for carrying, useful for quick attachment and able to hold the rolled bottle closed.
• Pack-pocket fit: the bottle remains upright and easy to store in common side pockets while filled.
• 42mm filter thread: compatible with many backcountry filters, including the HydraPak Filter Cap and Katadyn BeFree.
• Outdoor-ready construction: flexible TPU, POM components and welded seams are built for repeated use.
• BPA- and PVC-free: can be frozen and has a maximum recommended temperature of 60°C / 140°F.
