HydraPak collapsible water bottle Stow 350 ml, Sage Green, flexible BPA-free reservoir

The HydraPak Stow 350 ml in Sage Green is a collapsible water bottle with a flexible BPA-free reservoir that folds flat for compact storage. Designed for lightweight, space-saving hydration, the bottle expands to hold up to 350 ml of liquid and includes a leak-resistant cap that helps prevent spills during transport. The soft, pliable body reduces bulk when empty and the durable materials support repeated use for travel, outdoor activities and everyday carry.

Advantages

The collapsible design minimizes pack weight and volume, making the Stow 350 ml easy to stow in pockets, small bags or bike cages when empty. The BPA-free reservoir provides a food-safe drinking surface while keeping the overall unit lightweight. The leak-resistant cap and secure closure reduce the risk of accidental leakage, and the flexible construction allows the bottle to conform to limited spaces. Durable construction and reusable materials ensure long service life with regular care.

Suitable for

• Hiking and trail running where minimal weight and compact packing are important
• Cycling and commuting for space-efficient hydration on the move
• Travel and backpacking when saving luggage space is a priority
• Everyday carry in handbags, gym bags or jacket pockets

How to use

Open the screw cap and fill the reservoir with drinking water up to the indicated capacity. Close the cap securely to ensure the leak-resistant seal before stowing the bottle in a bag or pocket. When empty, squeeze out residual air and fold or roll the bottle flat to reduce its volume. Rinse with clean water after each use and allow to air dry fully with the cap off before storing to prevent odors or microbial growth.

Usage recommendations

For best performance, avoid storing hot liquids and do not expose the bottle to direct flame or high temperatures. Clean regularly with mild soap and water; use a bottle brush for thorough cleaning of the interior. When packing in a bag with other items, place the bottle in a separate compartment or protective sleeve to reduce wear on the reservoir and cap.
