• Travel scenarios where access to fresh hot or cold drinks is limited.

When it may not be suitable

This thermos is not recommended for extreme outdoor activities such as hiking or climbing where the unit might be subjected to heavy impacts or drops, as the internal glass insert is fragile and can break upon significant shock. Additionally, it is not designed for carbonated beverages, as pressure buildup can damage the seal or the glass interior.

How to use

To use the thermos, unscrew the lid and pour your desired beverage into the glass insert, ensuring you do not overfill it to allow space for the stopper. Secure the lid tightly to ensure an airtight seal. Before filling with hot liquids, it is recommended to preheat the glass insert by rinsing it with warm water, and conversely, pre-chill it with cold water for cold beverages to maximize thermal efficiency.

What to consider before purchase

Usage recommendations

To maintain the longevity of the glass insert, avoid using metal spoons or stirrers inside the thermos, as they can scratch or crack the glass. Always handle the thermos with care and avoid sudden temperature changes, such as pouring boiling water into a very cold glass insert, to prevent thermal shock.
