Klean Kanteen TK Wide Mouth Insulated Stainless Steel Water Bottle - 20oz, 32oz, 64oz Sizes | Leakproof & BPA-Free | Perfect for Hiking, Gym & Outdoor Activities

***************************FINAL UPDATE*******************************I've had this water bottle for three years now but haven't used it as a thermos for about the last year and a half. Ironically, the biggest problem with it--that it doesn't retain heat but instead radiates it quickly and powerfully--turned it into a good hand warmer on cold winter nights. We fill it with hot water, wrap it in an old gym sock, and keep it on our desk or in our laps. We discard the cold water and dry it out every day. Today, I happened to look inside to see if I could find out why it never kept beverages hot. I'll let you judge for yourself from what I found (see pics of inside of thermos air-dried overnight). We've never used any abrasive cleaners on this thermos--just mild soap, warm water and a vigorous shake or occasional pass with a soft silicone bottle-brush. But the interior has been peeling. In just three years. Hardly the lifetime use you expect from stainless steel. I wouldn't trust this brand anymore to hold our family's drinking water, let alone to keep our beverages hot.*******************UPDATE 2************************In the past month or so, I've had to stop using this thermos. I used to fill it with coffee in the morning as I began work, keeping it in the kitchen sink (lined with white porcelain that's now an ugly mottled brown from all the sloshing coffee since the lid doesn't pour smoothly...). But now the thermos' outside gets immediately hot to the touch and the coffee gets cold within a couple hours or so. I'll be on a call, then reach for some coffee. Lukewarm. Bleh.At the same time or just before I bought this Klean Kanteen "luxury" thermos, I'd bought a cheap 12-ounce stainless steel thermos (all ss, including the lid). I've dropped that thing a dozen times but up to now it keeps coffee hot far longer than the Klean Kanteen AND pours more smoothly (less of a mess). In this case, higher cost didn't mean better quality or customer service.I'm back on Amazon searching for a thermos with all stainless steel interior parts (including lid) but with a smooth-pouring spout. You'd think that with how popular coffee is and all the news about new, suspect chemicals in plastic leaching into beverages, a company would have already perfected such a design. I'll never trust a label that just because plastic is "BPA-free," it's safe. We've called Klean Kanteen FOUR TIMES in the past three months to find a solution. No reply. Sad we can't rely on Klean Kanteen anymore.*******************UPDATE 1************************I've been using my Klean Kanteen for over a year now. I fill it every day, even in the summer, with hot beverages. You can read my original review below about why I like Klean Kanteen, but over the past six months, I've found a major problem with my thermos. I fill the thermos with piping hot coffee and within thirty minutes, the outside of the insulated thermos is so hot I can't touch it. Even before I noticed this, my hot coffee was becoming lukewarm within just a couple of hours. I think something in the insulation system is broken. Disappointing.The minor problem I've discussed below--that the lid sloshes liquid all over the place no matter how carefully I pour. Since I'm working at home now, I keep the painfully-hot-to-the-touch thermos full of coffee in my kitchen sink and pour from the sink to make the inevitable clean-up easier.A quick note. Within the first week of getting my thermos, I contacted the company (Klean Kanteen) over my concerns with the lid. I even mentioned I'd be willing to buy an upgraded thermos (one with a pour-through lid) if they could reassure me that one would pour better. They "noted" my concerns but said nothing else. This company used to have stellar customer service--and that's what kept our family going back for our thermos/water bottle needs. But even before the pandemic hit, Klean Kanteen seems to have gotten large enough not to be invested in working with customers to solve problems anymore.All in all, I'm really sorry that I can no longer recommend Klean Kanteen. I've been with them for about a decade, but our latest experience with this 32-ounce thermos and the company's customer service representatives (June 2019) have prompted us to look for another stainless steel bottle supplier.******************Original Review***********************I've gone through about a dozen stainless steel water bottles in the last 20 years--four of which I still have/use. This is my third Klean Kanteen product. I often try to save money by buying something cheaper but I always get burned in the end doing so. My other "stainless steel" water bottles all have rust spots inside them. My oldest Klean Kanteen bottle, a single walled stainless steel bottle, is about ten years old and is still kicking, true to this company's advertising. I traveled all over Asia with that bottle and even dropped in from great heights while hiking mountain paths. And it has returned, whole, with me to the US. One of my older Klean Kanteen insulated bottles (small, 12-ounces) finally died about seven years into owning it. I must have left liquids inside it too long too often because it fell apart at the bottom. I take responsibility for that.After another cheap stainless steel water bottle's cap failed on me recently (flooded with water inside, unable to remove it), I noticed it was covered in rust inside the bottle area in under a year of use. I'm sure the massive intestinal troubles I had recently that coincided with finding the sloshy bottle cap resulted from my drinking contaminated water... So I returned to Klean Kanteen. This time I'll be more careful with this bottle and dry it out thoroughly between uses. I also won't submerge the lid as that seems to be the weak point for most bottles.So far (just received), I especially like the bottle's tight cap seal--with TWO silicone rings and Klean Kanteen's new screw-cap system. The cap screws on without a hitch even if I slightly misalign the body and cap. As I type this, the bottle is sitting upside down full of hot liquid on my desk. While there was initial dripping, once I tightened the cap until I couldn't tighten it further, the dripping stopped. I hope the need to tighten the cap so much won't lead to structural failure. The cap's sides are plastic but the surface that abuts the liquid is stainless steel surrounded by one silicone ring. I do notice the plastic is wet when I unscrew the cap so I think liquid is coming into contact with the plastic then falling back into the main compartment below. I really dislike plastic caps inside the water bottle at all and it surprises me Klean Kanteen didn't engineer a stainless steel cap option for this bottle.One other caveat, for me, is also a plus: the nicely rounded lip of the bottle. While drinking from the machine-smoothened lip is very comfortable, I'm finding it hard to pour without spilling liquid. I work partly from home and partly from a university. I always have my bottle with me in class or in my office in my lab. These are very bad places to spill things... I'm not sure yet how to solve this concern. I could have invested $10 more in Klean Kanteen's upgraded thermos with "pour-through" (lid) function, but I thought this bottle would suffice. Hopefully Klean Kanteen will have an idea how to solve this problem.So if it's not a huge deal for you that pouring hot liquids might lead to some spilling, and you don't mind the plastic sidewalls of the bottle cap (I'm already looking for an all-stainless steel cap replacement like my other Klean Kanteens bottles' caps), this is a solid bottle. And the company's warranty is outstanding. How do I know? I've called them in the past about another bottle and they went above and beyond to take care of me. That kind of customer service earns my business for life. You can feel safe investing a bit more in Klean Kanteen's higher quality products AND their commitment to actually helping their customers (instead of just processing orders).All in all, I'm happy with the purchase though I'll be looking for a better cap, if the company carries one yet. I'll update my review if anything major changes.I do not work for Klean Kanteen nor did Klean Kanteen send me any promotional items or compensate me in any way to write this review. I have become an avid user of Klean Kanteen products ever since visiting their website and reading all of the information about their company practices. I love this 20 oz TK Wide water bottle. In my estimation the wide loop cap is the best lid to use with this bottle. The cafe cap works just fine. But I prefer the better insulation properties of the wide loop cap. Absolutely no leak issues at all with the wide loop cap. Yes of course you do have to unscrew the cap to take a drink, but big deal that doesn't bother me at all. The 20 oz Klean Kanteen TK Wide is my go to water bottle. It fits in every cup holder in every car that I have been in. It fits well in the side mesh pocket of all of my backpacks or sling packs. It keeps things cold or hot for a long time. In fact they work so good that I have three of the 20 oz TK Wide's, 1 32 oz TK Wide and a 64 oz TK Wide on the way. The 64 oz will be used to hold ice all day while I'm at work or as a beer growler for craft beer on the weekends. The TK Wide works so good at keeping liquids hot that I use the 32 ounce to keep my green tea warm throughout my work day. I pour 8 oz glasses at a time and at the end of the day the last 8 oz cup is still warm enough to drink. I use one of the 20 ounce one's to carry my green smoothies to work. No matter what your needs are to keep things hot or to keep things cold Klean Kanteen has you covered and they are as good as Yeti or a HydroFlask. Klean Kanteen is a great company. In fact out of all the many different brands of insulated water bottles that are out there, Klean Kanteen is the only one that I have seen that donates 1% of their annual sales back to nonprofit companies that work on climate change and environmental issues. They are climate neutral certified and a certified B rated corporation. They use high efficiency solar panels at their corporate headquarters in Chico California. They are also the only water bottle manufacturer that purchases carbon offsets and renewable energy credits. If you are a person that cares about the climate and improving the environment, then choosing a Klean Kanteen product is worth your time and money. I have also been to Yeti's website and Hydroflask's website and haven't seen anything about donating proceeds back for climate change, purchasing renewable energy credits or carbon offsets, being a B rated certified company on any of their websites. Which is one the reason's I decided to buy from Klean Kanteen.Easy to clean, so happy it's more purple than pink.I like the TKWide bottles and cap system. I just wish it came in a single wall version with the same caps. I don't understand the consumer obsession with insulation. I make my drink in the morning and burn myself on it hours later. I want to enjoy my tea not wait all day for it lol. Still, it's a good product.*UPDATE* After reaching out to the company, they quickly got back to me to help resolve this issue. Ill bump my review to 4 ⭐️ for now. The customer service alone is great. The bottle is great. Just a small oversight that can be fixed remains.———————————————————————Ive had this Kanteen for almost 2 years. Theres not much room for complaint. The reason im writing this 3 ⭐️ review is because overtime, the TKWide bottle cap may leave black residue on the rubber gasket that comes in contact with the tip of the bottle.Id have to imagine this black residue is not safe for consumption as it could easily fall into the water bottle upon opening or closing the bottle.Hopefully someone at Kleen Kanteen is aware of this and are taking steps to resolve it. Id happily give this a 5 ⭐️ rating if they could prove they are fixing this issue. For now 3⭐️ Is justified.Cool bottleKeeps hot for longer than othersI originally bought these locally but they don't sell the anymore. I go this although smaller than the ones we have for our adult daughter for Xmas. We love this make as I can only drink Coffee or Tea hot and I mean HOT.This make is THE only make that keeps it hot enough and long enough for me. I have even bought 'Stanley' but they don't make those like they used to do,drinks are barley warm after about 3 hrs,even the thermos flasks. I will always buy KLean Kanteen from now on,the best ever for keeping hot for at least 8hrsVery convenient to use for hot and cold liquids. Easy to seal, easy to open. A little inconvenient to clean because it must be taken apart, but I think that's a function of the extra convenient and leakproof opening. I also like that it is easy to use as a tumbler, which you could not do with their old design because it had a sharp top edge.Lo compré para llevar agua fria en verano, en Aranjuez (tenemos unos veranos de morir). Aguanta perfectamente el dia completo estando muy fria, lo cual es de agradecer.Lo probé una vez con agua caliente para el té y me pareció que no aguantaba tanto el calor, pero es un termo realmente de buena calidad.
