64oz TKWide

A big upgrade over the no-name thermos I got from Home Depot around 5 years ago. The rubber knurling on the cap was glued on, broke free, and neither super glue nor Loctite could keep it back together. The flimsy plastic carry handle snapped in half and poked me every time I picked up the thermos. The threads and cap were always a pain to clean, and I was never able to confidently clean all of the nooks and crannies. This model solves all the gripes I had with my old thermos. The unique thread pattern is much easier to access and clean compared to traditional threads, and are surprisingly smooth to operate. You can open and close the cap most of the way just by spinning it like a spinning top. The extra insulation on the cap reduces plastic contact and keeps drinks cold/hot for significantly longer. The carrying handle feels sturdy, and is one of the few brands I've seen spend the extra few dollars on production costs to provide a METAL carrying handle, even at this $40 to $60 price range. It doesn't come with a lid you can drink through, but with how easy it is to twist off, it's not a problem. The brand offers multiple different lids with straws/spouts if you want to get one later down the line, which I can appreciate even if I do not currently plan to purchase any of these. It's wild to think that with most other brands, you have to purchase an entirely new thermos just to get a different lid. The thermos itself has a really nice curved lip that makes drinking straight from the bottle very comfortable, and I don't have to fight the bottle to keep it from dripping out the sides as I drink. I really wanted a simple, robust, easy to clean thermos with no lead and minimal plastic - this fits all the bills. Insulated containers really are a case of "you get what you pay for". Spending the extra $20-$30 on these nicer brands really are worth it if you're going to be drinking your water out of it every day. Only downside is that Klean Kanteens are made in China, but it's hard to find anything that isn't these days. Regardless, I can easily see myself using this thermos daily for the next 10+ years. One month update: Still love this thermos. I found out later that Klean Kanteen doesn't use any lead in their insulation solder. I'm surprised it's not a boasted selling point after it became fairly common knowledge that most thermoses use lead solder that can leech into the contents if you break the seal from a bad drop. It's nice to have the peace of mind that I'm not going to get lead poisoning from the fairly expensive thermos that I love so dearly. I got the "Kemi-Moto water bottle holder/carrier", the fabric and the handle make a larger sized thermos like this much easier to pick up. It also has a sling and a bit of extra insulation. I just use this thermos for water, and I consistently finish my drink before it warms to room temperature. It's freakish how long drinks stay cool in this thermos. It also still feels as rock solid and premium as it was new. I clean it every couple weeks with a vinegar rinse and a dilute vinegar + baking soda soak for 6-8 hours. The threads are easy to wipe down with a paper towel and don't require any special brushes. One of the best purchases I've ever made. That said, while the thermos is very comfortable to drink from 90% of the time, I've found the 10% of the time I take a drink while laying down, it's much easier to spill a bit out the sides. I'll take a few drops of water on my shirt over a harder to clean cap though.

I purchased this item back in May 20 25 and it’s perfect for everything that I want to stay cold like cold water from home here in Connecticut that absolutely tastes excellent and while visiting Pennsylvania in certain areas, like Lancaster, Pennsylvania, their water just doesn’t taste as good unless it’s filtered. This stainless steel thermos model is perfect for me because this insulated thermos is definitely leak-resistant, very easy to clean in the dishwasher or by hand. It may be a little weighty for some people but I love it. It will keep your cold water cold ( I add ice for good measure), it does keep your hot drinks hot, which is a big plus. I did mistakenly leave it inside a refrigerator at the Marriott Townhome Suite Lancaster Pennsylvania that we were staying in for one week and I wanted it back so bad that I paid paid a delivery fee of $24 to retrieve it and have it shipped back to me which is cheaper than buying a new one. It’s a little too big for my wife to use so I’m going to purchase her a smaller size. I keep it filled up by my bedside and have water to drink whenever I need it instead of running to the kitchen or bathroom for water.

Expensive, but my god is this thing a beast. Keeps things cold without refrigerating them, holds a lot, no dents or leaks. I've had it for 3 months and my only complaints are the handle is uncomfortable and the cap is somewhat hard to clean, but other than that it's incredible.

Exactly as expected! You can't beat Klean Kanteen quality and I prefer it over yeti. It is solid, well made and toxin free! I have been using it to keep coffee hot after brewing and it preforms perfectly. Highly recommend!

Stays cold for days even on hot days

I really liked this 64oz bottle. But one day it stopped keeping ice for more than a couple of hours. I guess the seam at the bottom got a leak, and it's not vacuum insulated anymore. Very disappointed in Kleen Kanteen. Update. Kleen Kanteen is sending a replacement bottle, at no charge. Thanks Kleen Kanteen! Update. It been almost a month now and still no replacement bottle. Kleen Kanteen says, sorry but they are having technical issues. What a bunch of crap, If I order another on on Amazon I would get it tomorrow.

The quality of this bottom is awesome but it’s a vacuum bottle. Water won’t get colder in the refrigerator. lol. It will keep already chilled water a long time. Unfortunately that wasn’t my intended application

I absolutely love Klean kanteen! While my friends have gone through a few hydroflasks over the years I have been going steady with my original green 64 oz uninsulated canteen for 9 years!! I literally take it everywhere until recently when I started getting slightly embarrassed to take it out during work because of how beat up it is (I’ll retire it to hikes and camping only) I finally decided I deserve an upgrade and Klean kanteen deserves my business once again! I wanted to stay with a 64 oz and this time for the insulated version. I knew it would be much bigger than my original but I was pleasantly surprised that it actually wasn’t! Not bad if you ask me. I also decided to just get the all stainless steel version so that the scrapes and dents over the next 9 years won’t be so noticeable ;)
