0.5 liters (17 oz)
For the first time an insulated bottle in the original SIGG Design. Double walled made out of high quality stainless steel. SIGG conceived the bottle in such a way as to prevent the customer from drinking anything too hot or too cold. If the bottle is too hot refrain from drinking until bottle is lukewarm.
Here's what other sites are saying:
Pour hot or cold liquid in the Sigg Hot & Cool Screw Top 16oz Bottle. Sigg made this bottle out of stainless steel and decorated it with a fun design. Stainless steel means the Hot & Cool Bottle won't leach yucky BPAs in your hot beverages, and the double-wall construction helps keep icy sport drinks cold and morning wake-up drinks hot. If this stainless steel Sigg bottle feels too hot, wait until the bottle is lukewarm before taking a swig.
Modeled after the original SIGG bottle design, the SIGG Hot and Cool bottle provides insulated storage for your favorite beverages. Double-wall stainless-steel construction keeps liquids hot or cold for hours; quality stainless-steel body won't affect taste and endures everyday use. Not sure if your beverage is too hot to drink? SIGG designed the bottle so you can just touch the outside to find out. When the bottle is lukewarm to the touch you know your beverage is ready to drink. Use to fill your mug or drink directly from the bottle. Please note: Bottle may become very hot when filled with hot liquid; do not put in dishwasher or microwave; not to be used for fermenting liquids.
