Flux™ 750ml

$18.09 ~~$27~~ In stock

Flexible bottles get an upgrade. The Flux is shaped like a hard bottle, compresses like a softflask, and cuts weight by 50%. Topped with a dust cover and twist-drink nozzle for grab-and-go hydration, plus a bail handle to keep hydration secure in your hand or on your pack. The Flux stands upright like a hard bottle but when you finish your drink, this bottle packs down to pocket size.

I wasn't sure about the twist-drink nozzle at first, but it makes sipping on the move so much easier—no fumbling with caps. The dust cover is a nice bonus for keeping it clean in my pack.

Squeezed this flat after a long trail run and it barely took up any room in my pack, which is exactly why I switched from a rigid bottle. The 750ml size lasts me a whole afternoon and the twist nozzle doesn't leak when it's rattling around.

The dust cover on the nozzle is such a small thing but it keeps the mouthpiece clean in my bag. It feels like a hard bottle in my hand yet weighs almost nothing when full.
