HydraPak Stow™ 1L Collapsible Bottle

The HydraPak Stow™ 1L is a pocket-friendly collapsible bottle for hiking, fishing, skiing, travel and everyday outdoor hydration. Its soft body conforms to pack and clothing pockets, while an internal baffle gives the full bottle enough structure to hold comfortably. When empty, it flattens and rolls into the bail handle to take up very little space.

Key Features

• Pocket-sized profile: soft construction fits places where a rigid bottle feels bulky and helps reduce bottle bounce while moving.
• Internal baffle: adds structure, improves grip and creates a slimmer profile when the 1L bottle is full.
• Roll-to-pack design: flatten and roll the empty bottle, then secure it neatly using the flexible bail handle.
• Leakproof flip cap: the easy-open cover protects the self-sealing silicone nozzle between drinks.
• Easy to carry: the bail handle supports comfortable carrying, quick attachment to equipment and easier filling from suitable water sources.
• 28 mm filter compatible: connects to most 28 mm threaded filters, including the HydraPak 28 mm Filter Kit; filter sold separately.
• Durable flexible construction: made from TPU, polypropylene and silicone for repeated outdoor use.
• BPA- and PVC-free: designed for reusable hydration.

How to Use and Pack

Fill the bottle, close the cap securely and use the bail handle to carry or attach it. Open the protective flip cover to drink from the self-sealing nozzle. When the bottle is empty, flatten it, roll from the base and tuck the rolled body into the bail handle for storage.

Cleaning and Care

Rinse after each use and clean with warm water and mild soap when needed. Pay attention to the silicone nozzle and underside of the flip cap, especially after flavoured drinks. Leave the bottle open until completely dry before storing it in a clean, ventilated place.
