How long does the warranty last for Coldest bottles, and what happens if the vacuum insulation fails?Updated a month ago
The Coldest bottles are designed to maintain cold temperatures for an extended period, and experiments have shown water staying cold for a substantial timeframe. However, if after filling your bottle to the top with ice and then water, the ice melts within a few hours, this may indicate the vacuum insulation layer has been compromised. In such a case, we can arrange for an exchange or provide a new Coldest bottle. It is important to follow the proper usage instructions to get the longest cold retention from the bottle.
