HydraPak Stow Mountain 500 ml collapsible water bottle in Mammoth Grey is a lightweight, reusable hydration solution designed for outdoor activities and everyday carry. The bottle folds flat when empty to save pack space and expands to a full 500 ml capacity when needed. Constructed from flexible, BPA-free materials with a secure screw cap, it provides a compact option for hiking, trail running, travel and commuting where reducing bulk is important.
Advantages
The collapsible design reduces storage volume when the bottle is empty, making it easy to stow in a pocket, pack sleeve, or luggage. Its screw cap offers a reliable seal to help prevent leaks during transport. At 500 ml capacity the bottle balances portability with sufficient hydration for short to medium activities. The lightweight construction minimizes carried weight while durable materials resist punctures and repeated folding.
Suitable for
- Day hikes and mountain trails where pack space is limited
- Trail running and outdoor training sessions
- Travel and commuting when a compact reusable bottle is preferred
- Indoor gym sessions or short cycling rides

How to use
Open the screw cap to fill the bottle with water or an appropriate cold beverage, then tighten the cap securely before stowing. When empty, drain any remaining liquid, shake or wipe dry, then collapse the bottle flat and secure it in a pocket or pack to save space. Rinse the interior after use and allow to air dry with the cap removed to reduce moisture buildup. Avoid filling with hot liquids unless specified safe by the manufacturer.
Usage recommendations
For long-term maintenance, rinse and air dry thoroughly between uses and store the bottle open or collapsed in a clean, dry place. Inspect the bottle periodically for signs of wear, punctures or degradation. Use the screw cap properly to maintain leak resistance, and avoid exposure to high heat or harsh chemicals to preserve material integrity.
