Klean Kanteen Classic Stainless Steel Single Wall Water Bottle with Klean Coat and Leak Proof Cap

I have owned a 27oz Klean Kanteen bottle for over 4 years now and like it so much, I decided to puchase the 64oz for work so that I won't have to take as many trips to the water cooler. I also purchased this because I went through a total of 3 glasses at work and was tired of breaking all of them. As expected, this thing can get heavy when it is full. The good news is that it was only a couple of bucks more than the 40oz and if I really want to, I could just fill this 2/3 the way and end up with a lighter bottle. Within 4 hours, I start to feel the water get warm, but at that point more than half of the bottle is gone. Ironically, I do not find myself drinking more water daily as I thought I would. I guess having it on hand doesn't always mean I will drink more. The bottle is very stylish and extremely affordable on Amazon.Getting back to the 27ozer that I had for years. It was painted and most of the paint is still on it. The color on the bottom of the bottle wore off after only a few months, but the body stayed good until recently when it fell behind the bed-frame and peeled off on the metal. This is to be expected since it was against sharp metal and you know what, I am glad that happened because it just proves that the bottle is resilient and didn't puncture when pressed against the sharp edge of the bed frame. Due to all of this, I decided to get grey this time and am happy with my purchase.Some people say that you get a metal taste. The only time I have noticed this is when I wash the bottle out with Hot Water and instantly pour cold water in it and then drink it. Give it about 5-10 minutes to get back to temperature or rinse it a 2nd time with cold water in-between.My only real gripe is the official Klean Kanteen tops. At the time of writing this review, they offer the plastic loop tops that come with the bottles, the sports caps that sometimes come with the bottles or can usually be purchased for $5-6, and the bamboo top which is basically the same thing as the plastic top except it is more nature friendly and stylish. I now have 2 sports caps on my bottles because I was tired of unscrewing it every single time I wanted water. The Unfortunately thing is that the sports caps get white build up on them after a few weeks of use. It can be washed off, but is very difficult. I am unsure if this is dried water on rubber or dead skin (yes gross I know), but I just wish they offered a better solution. I tried a 3rd party cap and it worked great in terms of not having these issues, but it was expensive and didn't provide the same flow of water which eventually just turned me off and led to me using the sports caps again.All in all, I love Klean Kanteen. I know that Hydroflask is the new kid on the block and most people have those, but I will always have loyalty to this brand and will continue to buy them as long as they still sell them. Heck, I might not even have to. These things may outlast me.

These stainless bottles are wonderful and well made. They are not made for heat/cool retention but I was not looking for an insulated bottle. I use these to cool off hot beverages quickly by putting hot beverages in them and running them under cold water and they work perfectly! Then I just keep them in the fridge and they take up much less space than the insulated bottles do. Thank you, Klean Kanteen!

It's large but you get used it. Wide mouth opening makes cleaning pretty easily. Not sure why there is a rating for 'Warmth' - this is not designed to hold hot liquids. Don't do that, you will burn yourself. Overall, really great quality and great brand for reusable water bottles. I am using it right now.

It's great for carrying hot or cold liquid, in a pours without spilling and it's easy to drink from. This is not insulated, that's the trade-off for the light weight. Though I have heated up my drink over a campfire, that voids the warranty.

Bought this because I was sick of plastic water bottles. This thing is awesome. The water tastes great, it stays clean a long time, it's extremely durable, and I only need to refill 2-3 times a day since it's so large.

Great water bottle. Dropped it and dinged slightly. However happy drinking out of a safer container. Have in two sizes and am happy with it. Use everyday.

Wide mouth isn't the easiest to drink from when driving, but it's not harder than the wide mouth Nalgene I've been using for years. Haven't tried any of the other lid/spout options yet. I do like that the water tastes fine, even if I leave it in the car for a few days. My Nalgene plastic bottles always had a little plastic taste after a few days. Love the durability.

By "companion", I mean that it will probably not be the only water bottle you will ever have. Its size (about 1.8 L) and potential weight (about 2 kg) mean that transport is not the easiest. I love using it at home or work to have easy access to water. When travelling, though, I might switch to a collapsible smaller water bottle or use two water bottles in conjunction.Pros:- All the water you will need in a day inside one bottle. I fill the bottle once a day and I am good to go.- The screw top is effective at both closing the bottle without the risk of leakage (but see the last con*) and for transport by hanging the bottle from a backpack loop or finger, etc.Cons:- Can be too big to handle for people with smaller hands.- * The advice to not put the bottle inside bags where there are other objects is silly (on the tag accompanying the product). The company might be protecting themselves in case water spills out inside a customer's bag, but that should never even be a risk. Considering this bottle weigh about 2 kg when full, I do not see how else I can travel with it, if not by putting it in a bag.
