The integrated flexible strap is designed to withstand frequent use, making it easy to attach your bottle to a backpack or carry it by hand.

- General hydration needs
This cap is not suitable for Hydro Flask bottles with a Wide Mouth opening, as the threading and diameter are incompatible. Additionally, it is not intended for use with carbonated beverages, as the pressure buildup can compromise the leak-proof seal and potentially cause leakage.

How to use
To use the Hydro Flask Standard Mouth Flex Cap, simply align the threads of the cap with the opening of your empty or filled bottle. Rotate the cap clockwise until it is firmly tightened to ensure a secure, leak-proof seal. When opening, rotate counter-clockwise. The flexible strap can be used to carry the bottle or to clip it onto a carabiner for hands-free transport.
What to consider before purchase
- Verify that your bottle is a Standard Mouth model before purchasing
- Check the bottle threading for any debris that might prevent a proper seal
- Ensure the cap is tightened fully after each use to maintain temperature retention
Usage recommendations
For optimal performance, hand wash the cap regularly with warm, soapy water and allow it to air dry completely. Avoid using abrasive cleaners that could damage the seal or the plastic components.
