A fantastically insulated flask great for staying hydrated whether you're looking for something cold or warm. I bought mine to carry hot tea up to mountain summits where it usually gets quite chilly. Not only would my tea be piping hot 7 hours after filling the flask but I actually had to wait for it to cool down! The same goes for cold water; ice takes hours to melt. At one point I remember having ice cubes still in tact a full day after filling it up! Great product that I highly recommend to everyone.

This bottle is awesome, I have left it in car for hours during Texas summer heat and the water was still very cold. I also love the fact that it does not sweat when you fill it with it ice cold water.

This is so cool! It keeps my drink really cold!! In the morning I put ice and room temprature water into my flask and the next morning it still had a small portion of ice!! Very cool.
