Aquatix (Turquoise, 21 Ounce) Pure Stainless Steel Double Wall Vacuum Insulated Sports Water Bottle with Convenient Flip Top - Keeps Drinks Cold for 24 Hours, Hot for 6 Hours

First I ordered the large size for when I work in the yard, it was a very hot summer in Boston, and I was out 4 - 6 hours a day. The water stayed nice and cold all day long. Then I ordered a smaller one for hiking, the smaller size has worked out well. A dear friend is a traveling sales person, she was commenting that she was in a huge traffic jam but had no water, as nothing stayed cold and she was concerned about having "heated" water in the car. So I bought her the large one. She adds ice to it and it has worked great. The other night it took her seven hours to get home from NYC, she was so grateful to have cold water to help keep her awake. Wonderful product, great price, fun colors. Thanks you for this amazing product.

This bottle is the perfect size and quality. The lid is leakproof and the opening for drinking is the perfect size so that you can chug water if you’re out exercising and are really thirsty. There is only one area in the whole lid that can harbor mold, and that is the rubber ring seal, but it’s easy to remove and clean well. It keeps the water cold for a long time too. I bought this bottle before moving overseas to live and it’s the best water bottle I’ve ever had. It comes with an extra rubber ring seal for the lid as well and the lid has a lock to keep it closed. This size is better than the larger size, since the bottle is kind of heavy due to its great quality, but in this size it’s not overly so.

I have had this water bottle for almost a year now, I have put this thing through hell! I may have left some small dents along the bottom, but the paint is still intact and the performance is in no way compromised. The only downside is the flip top is no longer a one handed operation. Even still I give it 5 stars because it still keeps my drinks super cold and has a great beverage capacity.

Excellent water bottle that keeps cold water cold for a very long amount of time. I had filled it with ice water in the morning and it was sitting in a warm to hot car most of the day and at the end of the day it was still very cold! It's durable and solid and overall a great buy.

I use this daily work for ups so when its 105 outside its a lot hotter in that cab and when i put water in it it will be cold the till u drink it all. It has lasted several hours in extreme heat and still cold plus no dust to drink with the way the lid is designed.

This product delivers. It does keep ice for 24 hours. It is remarkable. I purchased a second bottle.Absolutely love this bottle!!

Frequently leaks just a little at the top, requires careful screw-on of the lid

Great product! Kept ice for a long time! Took to theme park for the day and still had cold water by the end of the day.
