This Alfi Cool thermal bottle will keep its content hot or cold for 6-8 hours. The glass liner is made of double-walled alfiDur toughened glass. A vacuum is contained between the two glass liners, and a capillary seal keeps the glass liner air-tight so that there is NO direct heat transfer.
The Alfi Cool bottle has a transparent liner and a frosted outer container, so you can see the content through the frosting.
This bottle is ideal for taking 3-cups worth of iced tea or hot coffee with you to work or on a long drive. Or, keep a bottle of iced-water next to the bed when you go to sleep at night. This thermal bottle has many uses, and once you have one, you'll wonder what you ever did without it.
The Alfi Cool thermal bottle is an impressive 10.75" tall, and 4" in diameter.
