The lightweight, collapsible HydraPak Flux Flexible Bottle will appeal to backcountry hunters.HydroPak

The new HydraPak Flux Flexible Bottle—available in 1.5-liter (weight, 3.4 ounces) and 1-liter (weight, 2.7 ounces) options—offers a new take on the outdoor water bottle and provides an alternative to traditional reservoirs. The Flux was developed in an effort to provide an alternative solution to single-use plastic in the field and reduce the space and weight taken up by traditional hard bottles.

It is constructed to be free-standing, with dual-layer TPU film laminate and added embossed RF-welded soft walls that provide grip texture for ease of holding. The spill-proof twist cap allows for one-handed drinking, and the wide opening is compatible with all 42mm-threaded filters for easy refill in the backcountry. Empty, the Flux flattens, rolls, and stows into the bail handle to take up minimal space in your pack. SRP: $25, 1.5-liter; $20, 1-liter. (hydrapak.com)
