The HydraPak Stow 500 mL is a soft, pocket-sized water bottle for short trips, small packs and jacket pockets. It holds 500 mL (17 fl oz), and once it is empty it flattens and rolls up to stash in places a hard bottle will not fit. HydraPak rates it 50% lighter than most hard bottles.

A flip-top cap cover protects the high-flow, self-sealing silicone nozzle, so you can drink on the move without splashing. The integrated bail handle makes it easy to clip to a pack, carry in one hand, or dip into a lake or river to fill. Thread on a 28 mm filter and it doubles as a squeeze bag for backcountry water.

Key Features

• Pocket sized. The soft body conforms to a pocket and cuts out hard bottle bounce.
• Easy drinking. High-flow, self-sealing silicone nozzle under an easy-open flip-top cap.
• Packable. Flatten and roll it when empty, then stow it into the bail handle.
• Filter compatible. Attaches to most 28 mm threaded water filters, including the HydraPak 28 mm Filter Kit.
• Easy to carry. Flexible bail handle for comfortable carrying, quick attachment and filling at a lake or river.
