HydraPak Stow Mountain 500 ml collapsible water bottle, Sutro Green

HydraPak Stow Mountain 500 ml collapsible water bottle in Sutro Green is a lightweight, packable hydration solution designed for hiking, running and travel. The bottle holds 500 ml of water and features a collapsible body that reduces bulk when empty, allowing it to be stowed in pockets, pack pockets or small compartments. Constructed from a flexible, durable material with a leak-resistant cap, it is intended to provide convenient access to fluids on trails and during urban mobility.

Advantages

The collapsible design significantly reduces carried volume when the bottle is empty, saving space in backpacks and pockets. Its lightweight construction minimizes added weight for activities that require compact gear. The flexible material withstands repeated folding and packing while remaining resilient, and the leak-resistant cap helps prevent spills and maintains hygiene. The 500 ml capacity balances portability with sufficient hydration for short to moderate outings.

How to use

Open the cap and fill the bottle with fresh water up to the 500 ml capacity, then securely close the leak-resistant cap to prevent spills. When carrying, partially collapse the bottle as water is consumed to minimize sloshing and reduce volume. After use, rinse with clean water and allow to air dry fully before folding for storage to avoid moisture retention. Inspect the cap and mouthpiece regularly for debris and clean according to general hydration gear practices.

Usage recommendations

For best performance, avoid exposing the bottle to prolonged high heat or direct flame. Use with potable water only and follow routine cleaning with warm water and mild soap. When packing, place the collapsed bottle in an outer pocket or a dry bag to prevent contact with sharp objects. Replace if the material shows signs of excessive wear or damage.
