My favorite water bottle! This bottle keeps my water tasting fresh & cool for an extended period. I cant say for sure how long because Im constantly refilling it because the water is so refreshing. I did fill it up at bedtime & wake up to cold water, so I can guarantee at least 8 hours from personal experience.

I love that this is easy to clean AND doesnt sweat. My daughters have the regular Kleen Kanteen bottles any they sweat horribly. I find sweaty bottles annoying because they can damage papers in my purse and require coasters on wood tables. Bonus points to this water bottle for also being good looking!

I've owned this waterbottle for 2 years. It's been great. Ice water stays cold all day. The stainless steel interior is as pristine as the day I got it. The paint holds up pretty well to abuse, although if I bought it again I would probably just go with the plain brushed stainless one.

I'd recommend upgrading to the sport cap so you don't have to unscrew it every time you want to take a drink. I own several Klean Kanteen products and I am always a happy customer.

I am usually roaming around with my backpack which i carry my camera and my laptop in and i had a habit of buying bottled water and placing it in the side pocket of my backpack, so my wife got me this bottle as a gift and i just love it! it carries more water than a regular water bottle and it is leak proof. im enjoying it, i use it all the time now, before I sleep i fill it and keep it on my bedside table.

Love Klean Kanteen products and this was no exception! This bottle has been attached to me since it arrived. After starting with plastic CamelBak bottles (which broke really quickly and were difficult to clean) and then migrating to steel, I realized I should invest in a nice insulated bottle because I was sick of drinking water that got hot the minute I walked outside. This bottle is a great size, keeps my drinks cold, doesn't leak at all, and is easy to clean. I put ice in it over 24 hours ago, took the bottle in a kayak, let it sit in the sun, took it with on a long bike ride, and then let it sit overnight, and the ice is still in there!! I also think the color is really nice. I'm not usually the type to pick out a bright color, but this color is so lovely to look at and easy to spot among my belongings.

I'm really picky when it comes to my water bottles, but there isn't a single complaint I have or adjustment I'd make to this product.

UPDATE: I have had this bottle for several weeks now and was really enthusiastic about it when I first got it. I initially gave it 5 stars. However, after using it almost daily, I have noticed a real problem. Despite caring for this product very well and only using it as directed, there is an odor issue that just seems to get worse. The only way to describe the smell is like that of dirty gym socks and it makes the bottle almost unusable. I was already rinsing the bottle out after each use before the smell appeared. I have since tried cleaning it with vinegar, special cleaning tablets, different kinds of soap, etc. I even let it sit upside down and with the cap off for a few days to air out. Each time I clean it, the smell seems like it's gone and then as soon as I put water in the bottle, screw the cap on and then open it again an hour or two later, the bottle reeks. It's not the water either because I've used different sources of water. I cannot figure out how to get the smell to go away. I've pretty much given up on this bottle and started using an 8 dollar insulated bottle from Target. It doesn't keep my water as cold as this one, but at least it smells fine.

Just like the other Klean Kanteens but with more water volume - 40 oz - which is nice, because I was filling up the other one (27 oz) too often.

I LOVE this bottle! I'm OBSESSED with it. I ADORE it.  Okay, maybe a bit over-the-top, but I couldn't be happier with this water bottle. I bought mine in purple and a friend liked it so much I got her one in pink.

The bottle is truly operable with one hand. Simply grip it near the top and press the little tab on the lid and it pops open, allowing you to drink directly from the glass mouth of the bottle.  It even makes a cheerful little POOMP sound! The pitch varies with the amount of water in the bottle and it always makes me happy.

I have dropped this bottle THREE times on concrete--I even stepped on it once afterwards--and it's still perfect.  I have to admit that after I stepped on it, the lid was misaligned a bit and I was going to order a replacement lid, but then I noticed a little metal pin in the hinge of the lid was sticking out a bit. I lined up the holes in the hinge and tapped that little pin back in place. Good as new. Replacement lids are available if you're more klutzy than I am.  Speaking of the lid, it comes with a very sturdy cloth loop strap. I carry this thing everywhere. I've even used a little carabiner clip to attach it to my bag. The lid twists off for cleaning.

I wish it held a bit more water, but it would probably be pretty heavy if it carried much more because the glass is very sturdy. The bottle opening is not very wide.  It's much wider than the opening of a soda bottle and very easy to drink from, but the top edge of it can bump the underside of your nose. I really, really like it though, and if I ever manage to destroy it, I will absolutely replace it.

We recieved our first Kleen Kanteen as a birthday gift for our youngest son. I didn't think much of it until I started using it. It's wonderful! No straws to search for, or water squirting out when the spout flips up. The Kleen Kanteen is the perfect size for our sons lunchbox and keeps his water cold. It's Kleen (pun intended), simple and easy to use and clean. We loved it so much we purchased this new one for our other son.

I'm a big fan of Klean Kanteen water bottles. I've been using them for years. The stainless is easy to clean. The quality is top notch. The double wall insulation keeps the ice in my water from melting for many hours. This big boy gets me through an entire day without having to refill. Plus, I get a workout carrying it around all day. It's well worth the money to get a quality water bottle. I highly recommend their products.

18 oz Klean Kanteen. I purchased this item because it fits perfectly in the side pocket of my 5.11 PUSH pack. It holds water and is single walled.
Works great and is a great price.

I only like very cold water, and I have been trying to use less plastic, so I got a non-insulated Klean Kanteen awhile back. While that one sweats a lot and doesn't keep things cold for very long, this one doesn't sweat at all. I love it; I can fill it with ice water, close it up and sit it on my counter overnight, and there will still be ice in it in the morning. I worry that when I drop it, it will scuff pretty easily, but I have yet to let it slip out of my hands, so I can't say for certain on that. Also, the lid on this 20 oz. bottle is much easier to open than the loop lids on the smaller bottles. I recommend bigger ones for that reason. Overall, really great product.

This is my third one since I lost the other two! I really like this size (12 oz). It is well insulated and so keeps fluids hot and cold but interestingly, I find this size does not retain the heat as well as my larger Klean Kanteen. It is still a wonderful product!

I have had other stainless water bottles before, but they always tasted kind of, well, metallic. I got a smaller Kleen Kanteen for Christmas and fell in love. But it was too small. This 40 oz is the perfect size for me so that I don't have to constantly refill it. Also, the new design caps are MUCH quieter and flow more freely than the old ones. If you want a reusable bottle, Kleen Kanteen is the way to go.

Can't go wrong with an Earth friendly Klean Kanteen!  This will be perfect for my son to take with him on his hikes.

I bought two of these for my husband in an attempt to get him to stop buying and using evil plastic water bottles. Not only has he fully converted to his Klean Kanteens, he has told me several times that he really likes them! They might be a little pricey, but they're worth the cost as they keep cold beverages cold, especially when you add ice cubes. We haven't tried them with hot beverages yet.

I now own both the smaller and larger sizes of this Klean Kanteen. This product performs as advertised!
