Polar Thermal Insulated Water Bottle, Red, 24oz.

Excellent product! I will ride 40-80 miles at a shot, and this water bottle will keep the drinks cold for the entire ride. To this (as others have noted), you need to have "some amount" of liquid that you've frozen -- i.e., pre-fill the water with the mount of liquid you intend to freeze, put the water bottle in the freezer, and then (just before the ride) remove it from the freezer and fill the rest with cold liquid.Obviously, the more you freeze, the longer it stays cold. I use two of these water bottles; I freeze one of them half way, and use it on the first half of the ride; the other one I freeze completely, and (on a hot day) it's ready for use on the second half of the ride. That doesn't mean it has completely thawed by the second half -- but enough of it has thawed that I can start drinking, and the frozen/still-thawing chunk that's in there helps to keep the liquid portion nice and cold.These water bottles fit perfectly in standard bicycle cages. I loved mine so much that I bought a bunch for my wife and son (12yo, pretty serious road biker) -- and they are 'sold' on these water bottles, too!One last note: You will see in the picture that the water bottles come with carrying loops. As a road biker, I don't like any extra sh*t on my bike -- especially anything that adds to wind resistance. Those loops were the first things to go -- and BTW, they pop off (and back on) pretty easily. LUCKILY, I saved the loops, because when I purchased my wife's and son's water bottles, I (1) noticed how convenient they were for carrying the water bottles while also carrying a bunch of other stuff, and, thus, (2) decided that I could mount the water bottles, with the loops still on them, in such a way that they would not interfere with removing or reinserting the water bottles while riding, and also would not catch [much?] wind/add drag. And so now the loops are back on my water bottles, and I'm actually pretty happy with them. (I'm sure there are some who are reading this and saying, "Idiot. You should have figured that out in the first place." And they may be right. But for those who look at the loops and think, "Not On MY Bike!" I figured I would share my experience.)If you're a reasonably serious biker, I highly recommend these water bottles. They are the best thing to come along in biking since electronic shifting.... :-)

I am so disappointed by the Polar insulated water bottle. I bought it mainly for indoor use to keep the drink cool longer, and the supposedly non-sweating outside. It does keep the drink cool for a long time. I like to have it by my bedside table at night, and the drink stays cold even by morning. However, the outside of the bottle sweats a lot. It is wetter than anything I have used it the past. I thought that by it having double wall, that it will stay dry on the outside. Other reviewers even stated that it stays dry. Well this one sweats like a pig. It is unpleasant to hold because of the outside moisture. I am not happy at all. It is not worth the $15.99 cost. I could have picked a better one locally.

I tried to like it, but just can't. First, it is very hard to tighten to the point it won't leak. The collar interferes and you have to work it out of the way, and then tighten down very hard. Otherwise it leaks. It leaked the first 2 times I used it until I figured it out.Then, when you try to drink, there's no air exchange because you tighten it so tight, so you have to suck pretty hard. I don't like doing that. But, I stuck with it.But, if you leave water in it for more than a few hours, it tastes like plastic.Washed it and washed it some more to try to remove the plastic taste.Ended up with a different taste. More like a cocoa butter taste?I don't want any taste, I want to drink without hard sucking (or loosening the cap to drink), and I don't want it to leak. So, I took off one star for each.And if you are wondering, no, it doesn't keep things cold unless you put it in the fridge. Within 4 hours at room temperature, the water that used to be contain ice cubes, is now at room temperature.

Preface: For the first 8 months of having this water bottle, I would have given in 5 stars. When I went to write this review, I originally gave it 4 stars. After writing it, I realized it didn't quite deserve the 4 stars, so I lowered it to 3. Maybe 3.5.I loved this bottle when I first bought it in September of 2014 (just 10 months ago). I got the April Showers print, so it was cute and unique. I have never seen anyone with the same exact water bottle. It kept the water cool, it was easy to squeeze, so I wasn't left having to put too much effort into sucking my water out. (How's that for lazy?) I'm a college student, so I took this bottle to every class. I would drink a whole bottle about every hour while I was in class, so it was well loved. My only complaint was the mouth piece has "Remove" and arrows carved in it. I don't know what it is, but I end up with a white film inside the carvings. I can scrape it out with a toothpick or it flakes off, but I don't really know what it is. It could be the hard water we have where I am.The water bottle did me very well until about beginning of June 2015. It started leaking around the lid and the mouth piece wouldn't stay up. When I tried to drink, I had to hold it open with my teeth or else it would get pushed back in and I couldn't get water out. Also about that time, the outer layer cracked around the bottom of the hand hold place (where the bottle goes in), so now I have 4 cracks about 1.5 inches each. Maybe I squeezed it too hard or something, but I got these cracks. This wouldn't have bothered me, but now when I fill up my bottle, a teeny tiny bit of water can go through the cracks in between the hard outer shell and inner shiny stuff. It hasn't happened yet, but I'm worried about it getting some mildew down there.Anyways, 10 months later, I am now in search of a new water bottle. I would love to buy this again, but I'm worried about the same problems.
