The Flux™ may be the most versatile water bottle ever. It’s shaped like a hard bottle, stands up on its own, compresses like a soft flask, and cuts weight by 50%. The high-flow nozzle seals with a twist for leak-free transport and the flip-top cap keeps out dirt and contaminants. The structured design rides in packs’ bottle pockets without sliding around, then flattens to stash anywhere when empty. Its soft, collapsible design also makes it a great base for squeeze filtering. Flux 1.5L Twist-to-drink nozzle provides more flow and less splash than wide-mouth bottles. The dust cover protects the nozzle from dust, mud, and dirt. Flexible bail handle for comfortable carrying and a quick attachment point.
