I got this water bottle expecting it to be just that, a container for water, but was pleasantly surprised to see how amazing it really is.
The insulation in this bottle is really impressive. I put ice cold water in the bottle at the gym, went to work all day with it in the car, and after 10 hours of hot summer sun beating down on my black car, and interior temps over 100 degrees, the water was still ice cold.
I can't recommend this bottle enough.

Took this water bottle to the beach, and even in the sun for hours, my water was still cold. Really impressed with it.

This is my husbands favorite for work in the Summer His water stays cold all day every day. No more having luke warm to hot drinks, this does the job and working in a factory in 100 degree (f) gets you dehydrated. I need to get some more of these so there is always a back up and one for the rest of us. We finally found a way for him to have a cold refreshing water whenever he wants one without worrying about running to a store or finding a refrigerator.
