I love that this brand makes bottles with the safest material, no chemical lining on the inside, meaning it won't release toxic substance even when heated. I love that there are many colours to choose from, and many of them suit my taste. However the body is a little too soft, that can't withstand fallings. My bottles are having dents on the bottom after falling on the ground, making them difficult to stand on table. The lid is not leak free either, it will leak occasionally, I always have to make sure they are sitting upright in the bag.

Klean Kanteen compared to SiggOct. 30 2008
- Published on Amazon.com
Last month I bought a 40oz Klean Kanteen bottle and a 33oz Sigg bottle. In the end I prefer the Klean Kanteen.
Both bottles are very light and look good. The Sigg is lighter, but not so much to really matter. Sigg wins easily in the looks department with different artwork to choose from and the bottle I have has a nice textured powder coat finish compared to the KK basic look and smooth surface.
Sigg uses an epoxy to protect your water from the aluminum and tells you not to use the bottle for long term storage. Could be a bit worrisome not knowing what's in the epoxy and the possibility of aluminum contamination. I have not noticed a metallic taste from either bottle drinking straight unfiltered tap water. I prefer the stainless steel of the KK just because it's probably on the safer side.
The bottles are both lightweight and made of thin metal. I haven't dented either but I have been very careful with them. Both feel like they would dent quite easily. I have not scratched either bottle and the paint on both looks like new after daily use from work to the gym.
The KK bottle has the cap threading formed into the neck of the bottle while the Sigg uses a metal ring insert in the top of the bottle to thread the cap onto. Some people have complained that the Sigg's threaded insert is sharp, but I have not had this problem. The KK is more comfortable to drink from though. Also the wide mouth of the bottle makes it easy to put ice cubes in, which you can't do with the Sigg unless you have very small ice cubes.
I have the loop cap on both bottles. The Sigg I really have to twist the cap on tight so it doesn't leak. The KK cap seals quite easily and has never leaked. The KK also uses a thicker thread size and is easier to screw the cap onto because of this.
Some people are complaining about sweating. On a hot day with the bottles filled with ice cubes both will sweat, but plastic bottles will also.
If I was going to spend that much money on a water bottle again, I would go with Klean Kanteen without a second thought. The only advantage of the Siggs is the exterior design.
Update Dec 09: Over a year of use now and I have stopped using the Sigg due to their older bottles do in fact have BPA. Something they said it didn't have, so I won't buy another bottle from them again since it appears they were lying before. They will replace the older bottles, but you have to pay shipping.
I have 2 Klean Kanteens and both have held up well. Some minor scratches and dents, but still look quite good.

Good bye polycarbonate!Jan. 17 2008
- Published on Amazon.com
I purchased one of these for myself after researching the problems with polycarbonate bottles. At the same time I bought SIGG bottles for my kids because they had cool designs on them. Both brands of bottles are great and much safer than the polycarbonates. I like the Klean Kanteen much better than the SIGG for the simple reason that I can put standard ice cubes in it. I have yet to find an ice cube tray that is easy to use that will fit the smaller mouth of the SIGG.
With the Klean Kanteen I get clean water and no taste of metal or plastic or anything other than water. I fill this 27 ounce bottle 3 times during the day to make sure I get enough water. I like the sports cap, because I don't have to take off a cap and lay it down somewhere. I originally bought the bottle with a poly loop cap, but when I am teaching there is never a germ-free spot to set that lid down. So I bought a sport cap, and it is very easy to drink from.
If you buy the 27 ounce Klean Kanteen and like your water cold, I recommend a Built NY 20 oz bottle tote to use with it. The metal becomes VERY cold with ice in the water and with the bottle tote, it stays cold and your hands don't!

New Klean Kanteed, Not LIke the Old Klean KanteenApril 12 2010
- Published on Amazon.com
I first bought a Klean Kanteen in 2005. It was all it was cracked up to be. Sturdy, but light, water did not pick up a metal taste, it was easy to clean, and never leaked.
In early 2010, I decided to spring for a second bottle -- smaller this time, and with a nice painted color finish (not available when I got my first KK in 2005). Immediately upon receiving it, I could tell something was different. It felt thinner -- cheaper. Sure enough, I could squeeze the neck of the bottle and "squish" in the sides. I tried this with my original bottle. No way! It wasn't budging. I added water and, wow! The water had a terrible metallic taste. I never had this with the original bottle. I washed them both and filled them both from the same water source at the same time. Yup -- metallic taste from the 2010 bottle. No taste from the 2005 bottle. I started to wonder if the materials were the same, so I grabbed a small but powerful refrigerator magnet and tried to stick it to the side of each bottle. Remember, Klean Kanteen claims that the bottles are made of "304 stainless steel which has a low nickel content." (To be exact, 304 Stainless has between 8% and 11% nickel.)
Anyway, anyone with any knowledge of metallurgy knows that a magnet should not stick to 304 stainless steel. And, as expected the magnet does not stick at all to the circa 2005 bottle. But the 2010 bottle, even with the paint on it? The magnetic latched right on, even with the the bottle was turned upside down!
So, this and the metallic taste and the cheap construction leads me to believe that Klean Kanteen is NOT using the materials (304 stainless steel) they claim to use in these bottles. This is a serious accusation and not one I take lightly. But it is a serious concern. KK stakes their claim on providing high quality stainless steel. If they are using another material, they are deceivcing the public by not disclosing this fact.

Yes it's safe, but I simply cannot get rid of the metal taste with waterJune 1 2008
- Published on Amazon.com
The Klean Kanteens are likely the safest reusable drinking container in the US right now. The plastic containers containing BPA have been found to be unsafe and there are some concerns about Klean's major competitor, Swiss based Sigg, which uses an unknown patented liner of some kind inside their aluminum bottles.
The issues with the Siggs are twofold. One, we don't know what the liner is. The Sigg company won't say what it is, although they insist it's completely safe. Two, if the liner fails (which Sigg insists it won't do) you've exposed your drink to aluminum which many folks have legitimate health concerns about.
Speaking of concerns, the BPA containing plastic is NOT what is used in the Kantean lids. The idea that the plastic lids (which would have only very minimal contact with the contents - if the bottle is laid on its side for example) is somehow dangerous is only theoretical at best. Likewise, the same for the Sigg bottle lining. Both, neither or one could be completely safe. We do know that the BPA plastic is dangerous and neither bottle contains that.
Unlike some other buyers, I have had zero problem with leakage. I've also found the somewhat wider mouth to be extremely practical for using ice, drinking, and washing.
However . . . I have owned my 27 oz. Klean Kanteens for a few weeks now. I washed and rinsed them (probably six times) before I ever drank from them. The water I tested tasted and smelled like metal.
I have since washed one of my Kanteens multiple times with boiling water (the stainless steel conducts heat so you have to be careful doing this) and cold water, and none of it makes a difference. I continue to smell metal and I taste metal when I drink water. I don't think this is dangerous in any way, but it is annoying and it severely limits my use of the bottles. I've found that I can only use my bottle for flavored drinks.
My sense of taste and smell is generally pretty strong so I suspect each person will experience something different. Other reviewers have said they can't taste a thing or they got used to the flavor and don't even notice it anymore. After reading reviews all over the net, however, it's a fact that there are many of us who simply can't ignore the taste and smell.
So what to do? Me, I'll keep the Kanteens for flavored drinks, but I'm going to go out and get a Sigg for water. There's no other choice at this time.
If you have a strong sense of taste/smell you might have a problem with Klean Kanteens. Don't make the same mistake I did by ordering a bunch of these without first knowing if you'll have an issue. I strongly recommend you purchase only one bottle at first to see if you'll have a problem. If you can't taste anything then you've found the perfect water bottle.

little bit of a dribble cupSept. 30 2008
- Published on Amazon.com
After reading recent information about Sigg not sharing info about chemicals used to line the interior of their bottle, we opted to switch to Kleen Kanteen for the stainless steel. There are pros & cons: 1) obvious pro - the materials are known to be safe 2) the bottles sweat where as the Sigg did not sweat at all 3) the mouth of the bottle is large enough for ice cubes but makes it a bit more difficult to drink out of -- kind of like drinking out of a 1qt gatorade bottle --- sometimes a little bit dribbles out. 4) My 18month old loves his bottle because its the same color (stainless steel) as his dad's. We got him the sport top instead of the sippy top - and he manages just fine. 5) the slim shape fits nicely in most cup holders and water bottle carriers
