Flux™ 750ml

I was skeptical about a flexible bottle that keeps its shape, but the dust cover on the nozzle makes it perfect for tossing in my gym bag without worrying about dirt. It compresses down nicely as I drink, which cuts weight noticeably on long walks.

The twist-drink nozzle is way better than the pull-top caps I've dealt with. It compresses down as I drink so it stops sloshing around in my pack, and the weight difference is noticeable on long climbs.

Didn't think I'd care about the dust cover but it's actually great for keeping the nozzle clean when it's rattling around in my bag. And the way it squishes down as you drink means it takes up barely any room once it's empty.
