Flux™ 1.5L

The twist-drink nozzle is way easier to use one-handed than my old wide-mouth bottle, and the dust cover actually keeps the grit out. It squishes down to almost nothing once it's empty, which freed up a ton of room in my pack.

Took this on a 12-mile hike and barely noticed the weight in my pack. The twist nozzle is handy since I can drink one-handed without stopping, and the dust cover actually keeps the grit out.

Wasn't sure about the whole "compresses like a softflask" thing, but it really does collapse down when empty, making it much easier to stash in a daypack. The twist-drink nozzle has a nice flow rate, no weird splashing.
