Amazon.com Product Description
Dishwasher-safe, eco-friendly, high-quality stainless steel water bottles from Klean Kanteen offer a great alternative to plastic and lined metal bottles. Constructed of food-grade #304 stainless steel, Kleen Kanteen bottles are BPA-free and 100 percent recyclable. An all-stainless steel interior, 18/8 stainless caps, and stainless steel threads mean the bottles won't retain or leach flavors, so you get a fresh, clean, crisp drink every time. Because Klean Kanteen bottles are constructed of food-grade stainless steel, they're not coated with a plastic or epoxy lining like aluminum bottles.

The new wide mouth line of bottles have an opening more than two inches in diameter, which makes filling, pouring, and cleaning the bottle a cinch, and the universal thread design works with most standard backcountry water filters without an adapter. With the Klean Kanteen Wide, you have even more earth- and body-friendly choices. They come in five sizes, ranging from 12 to 64 ounces, and all come in pure, shiny brushed stainless steel. The wide bottles are shorter and more compact than Klean Kanteen Classic bottles but incorporate the same slim design, meaning sizes up to 27 ounces fit in most cup holders. They also come standard with the Stainless Loop Cap, which works seamlessly with the S-Biner, so it's a snap to clip it right onto a shoulder strap or pack.

About Klean Kanteen
Before anyone else was making stainless steel water bottles for personal daily hydration, before the current widespread concern about health and environmental issues in relation to plastics, Klean Kanteen was cobbling together the first Klean Kanteen prototype from items bought at the local hardware store in Chico, California. In 2004, the first Klean Kanteen bottles were released because the company wanted to give people something better than plastic and aluminum--a lightweight, reusable, body-friendly bottle free of BPA; a bottle durable enough to last a lifetime; an easy-to-clean, easy-to-carry beverage container for people of all ages; a bottle that keeps drinks fresh and clean-tasting no matter how many times you refill it; a simple design engineered for function in every way. In those early days, Klean Kanteen shared bottles with people at music festivals, environmental fairs, outdoor recreation events, and other sorts of progressive gatherings.

Klean Kanteen has grown over the past five years from a tiny, upstart company to a leader in the stainless beverage bottle industry. During this time, it's also taken significant steps toward lowering the environmental footprint through consideration and adjustments in every aspect of production facilities and practices. Ensuring office paper is 100 percent post-consumer content, providing hand and dish soaps that are fair trade and eco-friendly, using Energy Star-certified office equipment--these are just a few of Earth-in-mind internal operations choices. This commitment to sustainability also extends to the very beginning of the production process, where Klean Kanteen has increased oversight and conducted third-party audits of factories to ensure they're meeting Klean Kanteen’s high environmental and fair labor standards.

Customer Reviews

Noxious green goo
I love the design of the bottle but I'm having a problem with some sort of bitter green goo on the lip of the bottle. It appears to be coming from the seam that is just above the threads about 3/16 of an inch below the rim.

When I got the bottle I washed it by hand using dish soap and hand dried it. I put water in the bottle, tested the water tightness of the lid, removed the lid and took a sip. There was a awful, bitter, salty taste and I noticed the green goo on parts of the rim. I thought perhaps it was an adhesive or something (it resembles the remnants of a sticker), so I soaked the bottle (but not the lid) in warm soapy water and thoroughly scrubbed the rim. I licked around the rim and there was no offending taste. I let the bottle air dry overnight.

The next day I put cold water from my fridge in the bottle and capped it. About 15 minutes later I removed the cap and drank some and the foul taste was back. I can clearly see the light green goo on the rim and threads. It was not there before I capped the bottle. It does not appear to be coming from the cap. I suspect that when the cap is tightened it is distorting the seam and this stuff is oozing out. It is gross and I suspect that it is toxic. I am not using much force when capping the bottle, just hand tight and easily removed.

I see one other review here mentioning this problem. I don't know if this only affects some batches of the bottles or what. It looks like this problem might only occur on the wide mouth bottles. You also might not notice this if you didn't drink from the bottle directly (like if you used a cup or a straw). I sent an email to Klean Kanteen customer support but I have heard anything yet (it's been two days).

*Edit* On the third day I received an email from Klean Kanteen asking me to send the bottle in for an exchange and so their QC department could look it over. They thought perhaps the green stuff was residue from the polishing process that got under the rim.

**Edit 2** I received the new bottle and it seems to be fine. I had taken pictures of the original bottle's rim and the new one seems to have a slightly different design. The original bottle had a slightly rounded rim that was a little thicker while the new one has a thinner rim with squared off edges. I don't know if that's a definitive difference or just a supplier variation but I noticed it right away. I'd give the bottle 5 stars if I hadn't had the initial problem, I guess 3 overall considering the hassle. Unfortunately I can't edit the number of stars after the fact.

Green substance under outer rim...
I don't want to say it, but I don't yet have a good impression of the wide-mouth Klean Kanteen bottle. I got one last night and have hand washed it (live in NYC, so no dishwasher) four or five times with a special bottle brush, only to still see a greenish substance under the outside lip of the bottle. I didn't notice it at fist, so I ended up drinking from the bottle for about an hour, noticing a lemon-like flavor. But on second thought, um, no thanks, KK! I'll add green oozy lemons on my own accord....

I'm about as "eco" as they come, so I have the patience to give the KK bottle a fighting chance and I'm dedicated to finding a good stainless steel bottle, but the average person is NOT going to be pleased with this right-out-of-the-box, elbow-grease-needed design flaw, to perhaps no avail (I still have to check it again when I get home). And the bottle definitely smells a bit metallic, which I'm not stoked about, though it doesn't taste it. So, I may just return this KK and find a new brand. [sigh.]

"Green" Indeed.
Alas, since SIGG bottles were revealed to be the scum of the earth, I have been looking for new bottles. I thought I found an answer with this, the Kleen Kanteen Stainless Steel Wide Mouth Bottle (I chose the 18 oz./532 mL size). As you can infer, this "answer" only provided more questions. The Kleen Kanteen Wide Mouth Bottle is BPA free, stainless steel, single-walled, durable, and the wide mouth makes it easier to clean. This makes it perfect as a portable, lightweight, and most importantly reusable water bottle.

However, if this is supposed to be some kind of Super Bottle, the green substance I found seems to be it's Kryptonite. If you haven't already, read the reviews by Scott SD, C. Perry, and BookWormMom. I have not tasted this "metallic taste" they are describing when drinking from the bottle, but after looking at the hideous rim, I chose to drink "waterfall" style. To be specific, when I drink from it, the rim does not physically touch any part of my body. I have taken this to mean that the goo is what is causing the corrupted taste.

What all our reviews have in common is our experience with the "green stuff". I have reached a conclusion--heat is what makes this green residue appear. After all, heat is a catalyst. When I received this package, it was rather warm and the goo was much more abundant then, as opposed to after it was washed and cooled down. The ooze seems to originate from the crevice between the upper and lower part of the outer rim. Although I don't agree to the source of the ooze theorized by "BookWormMom" (the lid), it is definitely there and definitely more than a random flaw or occurrence. I don't want to wind up a Teenage Mutant Ninja Turtle from being exposed to this weird green ooze.

The goo is also very stubborn. I use a soft-bristle baby bottle brush from Munchkin to clean all my bottles--including this one. The residue seems to leave a permanent, or at least incredibly stubborn, stain upon the ...stainless...steel. No amount of soaping, scrubbing, scouring can remove it. It is a whitish-greenish stain (similar looking to calcium deposits on windows) along the upper and lower part of the outer rim.

At this point, you can probably guess how I feel about recommending this bottle. So, if you are a victim to this mysterious ooze, or simply want to know what this substance is before you buy it, contact Kleen Kanteen [...] and complain/express your concerns. Hopefully there is a recall or at least a definitive answer as to what this substance is and where it is coming from.

In the interest of full disclosure, I ordered my bottle from bayinghound.com on the 26th of September, taking advantage of their "SIGG Replacement Program". I was hoping that my fellow reviewers could also comment on when they purchased these bottles and from which retailer (if not directly from [...]). Since all the reviews complaining about the green residue occurred within the month of September, it could be a certain shipment of bottles.

I would like to add that this is an issue specific to the "Wide Mouth" version of the Kleen Kanteen bottles, the "Original" version seems to be fine.
