Absolutely! The sleeve is vacuum-insulated to keep beverages hot or cold for a long time.
You can use your BOROUX glass water bottle in your Move Sleeve to keep cold drinks cold for a long time. Keep ice frozen all day long.
Borosilicate glass is resistant to temperature fluctuations (because it doesn't expand like regular glass). We recommend using the Move Sleeve for hot liquids only if you place the glass water bottle inside the Move Sleeve first before pouring the liquid into it, because the glass will be very hot.
