Flux™ 1L

$19.43 ~~$29~~ 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.

Finally got this on a long trail run and the compression ability is a game changer—fits in a tiny pocket once I finish it. Dust cover keeps the nozzle clean, which I appreciate.

Wasn't sure about the twist-drink nozzle at first but it's actually way easier than biting a softflask valve, no leaking in my bag either. The dust cover is a small thing that makes a big difference on dusty trails. Weighs almost nothing when it's empty, you barely notice it's in the pack.

The dust cover and twist-drink nozzle make it perfect for tossing in a bag mid-run — I never have to fumble with a cap while sweaty. And honestly, the fact that it compresses down like a soft flask yet stands up like a normal bottle is the best of both worlds.
