This bottle is amazing put water in it and put it in the freezer and it takes a couple of days to freeze and when it does it will take 24 hrs before the ice melt and the water will stay cold for may more hours

I did not expect this to be so great i ordered this just to hold hot water for tea which it does really well ive since tried it with cold water and it did even better no leaks in backpack wow great bottle its much better than my kleen kanteen because its insulated and much more co
