Rated 5 out of 5 by from The longevity of Klean Kanteens I purchased my 40oz Blue Planet colored Kanteen just about 7 or 8 yrs ago. I still love it. I drink from it at home, I take it to work and I use it in the car. I am in no way easy on this product, or anything for that matter. I have dropped, dented, bonged, banged, and clinked my Kanteen into so many objects that it no longer stands up without wobbling like a weeble. Large chunks of blue paint are missing from so many places that most of my family members have asked me if I wanted a replacement at one point and time over the past 5 yrs. In my mind those facts are just a testament to the durability of Klean Kanteen products. I would recommend this Kanteen to anyone looking for a excellent product.

Rated 5 out of 5 by from The best water bottle ever created! I drink a lot of water, like probably close to a gallon a day. I was always filling up these little 20 oz "cheap" water bottles and they wouldn't keep the water cold. Plus, they were not environmentally friendly. The 40oz Kleen Kanteen did the trick! I only have to fill it up 3 times a day to get my gallon in! And it keeps it cold and the spout is SPILL Proof. It also does not hold "flavors" I might add to my water for the next time I fill it. Some water bottles will hold whatever you put in it, (lemon, flavored packets) and its hard to get that flavor out when you just want plain water. Not these. Easy to clean. Keeps things COLD and HOT for a VERY long time. We have 5 in our house now.

Rated 5 out of 5 by from Over 12 Years and Still Going Strong!! I am amazingly impressed with your company! I wish every company held the high standard that I have come to expect from your products! I have had my same Classic 40oz. Klean Kanteen water bottle and cap for about 12 years now. It has seen many bumps and dings in years of daily use, but no issues to make it not able to be awesome! Just the other day I opened to drink and the metal bottom of my lid came apart from the plastic top part (I noticed this type of lid isn't sold anymore). My husband just clicked it back together and haven't had a problem again since! While my Klean Kanteen emblem has long since faded, my appreciation and respect for your company had only increased! I am so thankful for the high quality product you delivered! Thank you for all you do!

Rated 5 out of 5 by from You can run them over but you can't mow them with a tractor. The 40oz bottle is a fantastic size for someone like me who works outside 9 months of the year. Being an organic farmer I try my best to reduce the amount of uneccesary additives to my food and my drinks as well as own things that will last. It's wonderful to know that my bottle in no way effects the taste of my water. Especially after having made a home made electrolyte in it. I'll continue buying these bottles even if they may occasionally fall off the tractor and find their experation in the mower.

Rated 5 out of 5 by from The best water bottle on the market I absolutely love this bottle. It is the perfect size for a long day and it keeps the water relatively cold for a while even though it is not insulated. The purple color is beautiful and the sports cap is so much better than before. I previously owned a 20oz Klean Kanteen bottle and the sports cap always made a chirping sound that would be an annoyance after a while. I would recommend this water bottle to everyone! Plus it's made of the perfect materials so I don't have to worry about BPA and all the other chemicals other companies have in their plastic bottles.

Rated 5 out of 5 by from Classic 40 oz originally from the South West, I know the importance of staying hydrated. Now that I live on the East coast, with much higher humidity, one tends to forget about staying hydrated. With the 40 oz, I know I have to fill and drink it three times a day, it takes the guess work out of how many 8 - 12 oz glasses of water did I consume... Small thing to consider, however, every time I find a better way to stay healthy, I tend to do so. Thanks for providing this easy to use, easy to clean, and eco friendly bottle. Jim

Rated 5 out of 5 by from 40oz to Plastic Free Freedom I hate reviews that start off by saying how much the reviewer loves the product and that they just can't leave home without it but I love my klean kanteen and I just can't leave home without it. I have a black 40 oz klean kanteen with the sport cap which makes it easy drink from/carry around daily despite clunky first impression. I have dropped the poor thing too many times to count and it have surprisingly remained intact and with just a few dents, which I like to think adds character. It's easy to clean and eco-friendly so it's a win all across the board.

Rated 5 out of 5 by from Best bottles ever. I first encountered these bottles at a local health food store. A clerk directed me to them, as a great wearing, rugged and good looking bottle. So I bought 2. I've had them for years and have dropped them from 4-5 feet and they only show a few small dents. When washed they don't retain any soapy residue that can affect the taste of the water. I went on line to order a replacement top for one that broke and found out that they had a sale going on I bought 2 more, and several tops. Great bottles. Can't say enough about them.
