I came
this close to ordering the red 18 oz. Hydro Flask from
Amazon last week. I actually placed the order and hit submit and then cancelled the order two minutes later!
I just did not think I would like sipping out of the metal neck. My personal "fear" or something. I wanted a sipping flip top or a straw. I kept searching on Amazon and these were the two choices. Both are double walled thermal Thermos bottles. Keeps cold twelve hours, according to the label.

Both were $20.00 at Target.
I bought the first one. What won me over was the pretty purple floral design and the straw. Especially when I am driving, I do not like to tilt my head back.
I did a comparison at work with the bottle I used to use. Water and several ice cubes. After one hour, sipping some from each bottle, the new water in the new bottle was still quite cold, my old water bottle with a neoprene sleeve was only sort of cold.
Experiment two - ice cubes and water, several hours later, ice had melted, but
water still very cold.
I decided that keeping the liquid cold for
twelve hours was not really that important to me. I am never all that far from a source of cold water/ice. And at only 18 ounces, I'd better be refilling it more often than every few hours!
So as a bottle for
long term storage, maybe not.
For the convenience of having a cold one close by at my desk (such a pretty bottle!) or or in the car, it is great.
It would also be good to carry at WDW, stopping to fill it every hour at the nearest counter service eatery.
