Coldest Insulated Water Bottle with Handle Lid | Leak Proof, Simple Insulated Modern Stainless Steel, Double Walled, Sport Bottles, Metal Flask | 21oz

Coldest products are fantastic! They keep my drink cold or hot for hours! I bought my water bottle “used” at a significant discount, and I could not tell it had ever been used. Yay!!!!!

The Coldest Water Bottle: I do love this water bottle! All my other ones are obsolete now. I've had it for nearly three weeks and use it constantly. The 2nd day I had it, I was surprised to find the ice had not melted after it sat on the kitchen counter from the previous day. On the 3rd day, I had left the cap off intentionally the night before to melt the ice so I could wash it out. Much to my surprise, the cold just settled in the bottom of the bottle and the ice was still unmelted. I don't know how it's done but this little gem is ridiculously good at keeping some reserve ice so you can refill the bottle again and again for almost two days. The trick is to fill it with ice no more than half way so you have plenty of water before it's time to refill. Bottom line is I took a $20 gamble and it paid off beautifully. You'll be drinking ice cold water all the time too! It's worth it. PROS: Managed correctly, it will maintain enough ice to chill water for close to two days. It has a rugged powder coat finish. This bottle is very durable. The lid handle is very solid and secure. CONS: The Coldest Water Bottle is not huge by any means. You'll have to refill it often but the reserve ice will chill your water instantly. The black finish might cause more rapid ice melt in direct hot sun but I did leave it in my hot car for six hours while fishing - came back and it still had plenty of ice. You have to unscrew the cap each time for a drink but it is very secure with a silicone gasket. This bottle won't leak when it's on it's side. It's durability might be offset by it's weight which is a little heavy for long treks. I wish the drink through lid(sold separately) will become available soon on Amazon. The best improvement to be made to this bottle is to attach a rubber boot on the bottom. The thin powder coat finish is evident when you set the bottle on a hard surface from the metallic "ping" noise it makes. Won't be long though before I find something rubberized to fit snug around the bottom.

It was a great size. Keep the water cold for hours. Good price for the value.

I previously had purchased a different "insulated" sports water bottle for my bike that was much cheaper. After an hour of bike riding on a warm California day the water that started out cold was now hot. So, after looking at some reviews, I decided to take a chance on "The Coldest Water Bottle" even though it cost a lot more. I am amazed at how well the "Coldest Water Bottle" (which I'll abbreviate as "CWB") works! After a full day of bike riding my water was still cold. I decided to do some tests later. I filled the CWB with cold tap water, which was 76 degrees (F.) The exterior of the CWB was also 76. I then put the CWB outside on the ground in bright sunlight. The air temperature outside was 92. One hour later the exterior of the CWB was 111. Almost too hot to touch. The outdoor temperature was 96. The water inside the CWB was now 78. I left the CWB outside for 6 hours. The outdoor temperate got up to 102. The exterior of the CWB got up to 114. The water inside the CWB got up to 83. At the same time I also tested the other, cheaper, "insulated" bottle for comparison. After one hour, the exterior was 95 and the water inside was 91. After 6 hours, the water was 101. So I am very impressed by, and highly recommend the CWB. It costs 3 or 4 times more than a regular "insulated" bottle, but if you want a sip of cold water after some hours on the trail, the CWB will have it their waiting for you. Ahhh! My only complaints about the CWB are that the color is black, which absorbs more sunlight, which makes the outside of it get hot to the touch, hot to hold it in your hand. This would probably be a good thing if you keep hot coffee in it instead of cold water - it might help keep the coffee slightly warmer after some time. Also, the decorative blue rubber strip around the bottom is very flimsy and gets snagged on the bike's bottle holder when putting it in or taking it out of the holder. I just removed the blue rubber strip and threw it away (in a recycle bin, of course) rather than be bothered with it every time I get a drink of water. I would subtract one star and rate the CWB as four stars, but since it is so awesome for keeping my water cold, I give it higher than five stars for that! So subtracting one star from six for the minor complaints, still leaves the CWB rated five stars for me. A few observations about the CWB: Some reviews I saw on this product said the cap leaks. Mine has never leaked at all, but I do screw the cap on very tightly just to make sure. The CWB fits perfectly in your standard bicycle water bottle holder. It isn't heavy, but it is very solid and sturdy.You could probably drive a car over it without crushing it. But I'm not going to try that just to find out!

I personally can’t drink water unless it’s cold. My water stayed cold in this bottle for atleast 2 days, it’s so worth it. The ice melts but the water stays super cold still.

I bought my on sale bundle, but i did not receiving the lid and straw plus the straw washer, No problem with the bottle keeping water cold.

Die Flasche ist der Hammer würde ich jedem empfehlen. Gute Qualität und Preis Leistungsverhältnis stimmt auf jeden fall.

Sadly it did not even perform to specs, bottle sweats and ice no more cold.

Es una botella termica fenomenal, me encanta. Y llego muy rapido! Gracias!
