Cold Drinks
Cold beverages stay ice-cold for 8–12 hours under normal conditions. Ice often lasts most of the day, making this tumbler perfect for summer weather and outdoor activities.
Hot Drinks
It can keep drinks warm for several hours, but this tumbler is clearly optimized for cold beverages due to the straw lid design.
Cleaning & Maintenance
