Stay hydrated on the go with the flexible, durable and ultra-portable HydraPak® Stow™ 500ml. This handy water bottle is made of sturdy, safe thermoplastic polyurethane and unlike hard bottles, it conforms to whatever space you stick it in, whether that’s your back pocket or your hip pack. An easy-open flip-top cap makes it easy to grab a sip while you hike, and the spill-proof silicone nozzle ensures you don’t waste a drop. A flexible bail handle lets you carry it or attach it to a pack, and when the bottle’s empty, simply flatten it, roll it up and tuck it into the handle for compact storage.
