Stowable Hydration: HydraPak’s Flux Flexible Bottle

HydraPak’s Flux Flexible Bottle (available in 1.5-liter and 1-liter options) is a new take on outdoor water bottles designed specifically for backpackers and thru-hikers. HydraPak developed it in an effort to provide an alternative solution to single-use plastic on trails and reduce the space and weight taken up by traditional hard bottles.

It is constructed to be free-standing with dual-layer Thermoplastic Polyurethane (TPU) film laminate, and embossed RF-welded soft walls that provide grip texture for ease of holding.

The bottle is BPA-free and PVC-free, and meets or exceeds food safety standards.

We tried it out on a canoe trip and found it especially handy for a few reasons. One, it didn’t roll around on the bottom of the canoe. Two, you didn’t have to worry about denting it. We like stainless bottles but they are heavy and although they may be unbreakable, they dent fairly easily if dropped (or thrown around inside a pack). The Flux’s soft feel belies its very tough TPU construction.

Plus, the spill-proof twist cap allows for one-handed drinking on the go, and the wide opening is compatible with all 42mm threaded filters for easy refill in the backcountry. When empty, the Flux flattens, rolls and stows into the bail handle, taking up minimal space in your pack. This is a bottle that will never slow you down and will adapt with you on all your fast-moving adventures.
