In 2004 when we released the first Klean Kanteen bottle, the only other options out there were polycarbonate plastic bottles or aluminum bottles lined with plastic resin or epoxy.
The reason Klean Kanteen exists is because we wanted to give consumers a safe, healthy, BPA-free alternative to plastic, a bottle that's reusable, environmentally sustainable and durable enough to last a lifetime. We chose to make our bottle from high-quality, 18/8, food-grade stainless steel, one of the healthiest and most durable materials available.
Some of the key features that set Klean Kanteen apart include easy to clean rounded corners and threads; high quality, food-grade materials that are BPA-free and don't retain or impart flavors; and durable, all-stainless construction including bottle threads.
We also set up our company and our manufacturing to be environmentally responsible and sustainable from the beginning. We oversee our manufacturing every step of the way, from the sourcing of the basic materials to the retail floor and we're constantly working to cut waste and operate more efficiently.

Klean Kanteen has four main bottle lines: Kid Kanteen, Classic, Wide, and Insulated. The Kid Kanteen line currently consists of a Sippy for toddlers and stainless steel Baby Bottles. The Classic is the original Klean Kanteen, the one with the longneck design. The Wide is a wide-mouth bottle, and the Insulated has the same design as the wide-mouth bottle but uses double-walled, vacuum insulation for amazing insulating performance. Visit the Kanteen 101 pages to compare the Classic and Wide lines. We also offer the Kanteen Reflect, featuring no paint or plastic, as well as the Steel Pint Cup, with the goal of replacing single-use cups.
While aluminum is lightweight, it can leach harmful substances and chemicals when it gets hot or comes in contact with anything acidic. Studies have also linked aluminum exposure to Alzheimer's disease. To ensure that the drinks inside aluminum bottles are safe, the bottles must be lined with something.
The most common materials used to line aluminum bottles include plastic resins or baked-on epoxy, both of which can leach BPA and other harmful chemicals or can get scratched, exposing the aluminum underneath. Ceramic is another material used to line aluminum bottles, but it's more rigid and can crack.
Of even greater concern is the fact that many companies won't release information about what the liner on their aluminum bottles is actually made from. The liner can also retain flavors, which can make your drinks taste funky.
The stainless steel used to make Klean Kanteens is time-tested, safe and completely free of BPA, phthalates, lead and other harmful substances. It's fine for acidic beverages or foods, and doesn't retain or impart flavors. That's why it's the material most commonly used in food preparation and by the brewing and wine-making industries.
Klean Kanteen redesigned the sport cap, releasing the Sport Cap 2.0 in the spring of 2009. The Sport Cap 2.0 performs extremely well, delivering a high flow rate (3x greater than the original cap) with almost no effort. It's also much quieter than the old sport cap, though the air flowing back into the bottle as you drink does make a soft noise.
No way. Every Klean Kanteen ever made is totally free of BPA and other harmful substances.
The whole reason we founded this company was because we read the early studies linking BPA to a number of illnesses and we wanted to give consumers a safe, healthy alternative to plastic and lined aluminum bottles.
We chose 18/8, food-grade stainless steel instead of aluminum or plastic because the metal is inherently safe and toxin-free. Stainless steel is made of many elements and minerals that come from the earth, including some of the very same minerals recommended by the FDA as part of a healthy human diet.
Food-grade stainless steel is used in the brewing, food and winemaking industries too. It's the material of choice because it doesn't retain or impart flavors.
All our caps are BPA-free polypropylene (pp#5) too, and we offer stainless steel cap options.
No. All Klean Kanteen products are made from high quality, 18/8, food-grade stainless steel that's totally free of BPA and other harmful substances.
Because stainless steel is inherently safe, we don't need to coat the inside of the bottle with a plastic or epoxy lining, which is one of the main differences between a stainless steel Klean Kanteen and aluminum bottles.
We're proud to offer a range of premium, totally plastic-free cap options for our Classic line including the Stainless Unibody Bamboo Cap and our All Stainless Loop Cap.
Because our goal is to make reusable products at prices that are accessible to everyone, we also offer caps made from safe, BPA-free polypropylene (pp#5). These caps are lightweight, cost-effective and give consumers a lower-priced option that meets our high standards for quality, durability and design.
In the case of the Sport Cap 2.0, it's also a safety issue because people drink from their bottles while engaging in sports like cycling and running. Polypropylene is very durable, but it's also a softer plastic, which means you're less likely to damage your teeth if you hit a bump on the trail while you're drinking.
The wide-mouth Stainless Loop and Stainless Flip D-Ring caps have stainless steel on the inside, so the inside of the Kanteen is all-stainless, with drinks never touching plastic.
Klean Kanteen uses polypropylene (pp#5) because it contains no Bisphenol A (BPA), a chemical that leaches from some kinds of plastic and has been linked to various diseases. Polypropylene has no known leaching characteristics and is softer than other types of plastic.
Stainless steel is an iron-containing alloy made from some of the basic elements found on earth: iron ore, chromium, silicon, nickel, carbon, nitrogen and manganese. The properties of the final metal change depending on varying amounts of these elements. More than 57 stainless steels exist and are sold as standard alloys on the market.
Klean Kanteens are constructed from high-quality, 18/8, food-grade stainless steel. The numbers stand for the percentages of chromium and nickel in the steel, 18% and 8% respectively. Chromium increases the metal's hardness and nickel gives it strength. Together they also make stainless steel highly resistant to stain or rust.
Stainless steel is easy to clean, durable, inert and sanitary. That's why it's the material of choice among the food processing, dairy and brewing industries.
Nickel is a naturally abundant element found in the earth's crust, soil and ocean floor. It is generally resistant to corrosion and is therefore used to make metal alloys such as stainless steel.
Approximately 10-15% of the population is sensitive to nickel, but the health effects of nickel are highly dependent on the manner and degree of exposure. The stainless steel used to make Klean Kanteens has a low nickel content and is the preferred material used by breweries and dairies.
Stainless steel does not contain hexavalent chromium; so you don't need to worry about exposure to hexavalent chromium from your Klean Kanteen. Hexavalent chromium has been found in tap water in some municipalities. We recommend that you check with your local water provider and get a copy of their most recent water quality reports. They're public record and should be made available to you upon request. The tests may even be available online.
No way. When we introduced our painted bottles, we wanted to find a safe and durable paint that also looks fantastic. We reviewed and tested dozens of different paints and selected an acrylic paint that contains no toxins or lead. We test the paint regularly and though it is safe, we recommend the Brushed Stainless finish bottles for small children who like to chew on things.
No. The paint on Klean Kanteen bottles is a nontoxic, acrylic, resin-based finish that's mostly water and is totally free of lead and toxic chemicals. So you've got nothing to worry about if your child ingested some paint! That said, we do recommend the Brushed Stainless finish for small children who like to chew on things..
Klean Kanteen received six consumer reports relating to the spout tip of Sport Cap 2.0 breaking or cracking after being dropped, which could pose a potential choking or ingestion hazard. There have been no incidents of factual choking or ingestion reported.
We replaced the spout tip with a new one made from the same BPA-free, polypropylene, but the formulation is slightly different. The new spout tips are six times more impact resistant and stronger than the original spout tip on the Sport Cap 2.0.
Visit our Safety Notice page for information about the recall including how to identify if you've got a recalled cap and how to get your recalled Sport Cap 2.0 replaced.
The very first Klean Kanteen was created to promote healthy living and respect for the environment by giving people an affordable alternative to plastic and lined aluminum bottles.
Klean Kanteen has always shared many of the concerns you, our customers, have expressed about manufacturing the bottles in China. Before a single bottle was ever produced, Klean Kanteen set in place checks and balances to ensure that our bottles are produced safely, sustainably and that the people making Klean Kanteens are treated well and paid fairly. By manufacturing in China, Klean Kanteen can provide a handcrafted bottle of exceptional quality at a reasonable price.
For more information about our commitment to operating Klean Kanteen sustainably and manufacturing our products in a way that's environmentally responsible with fair labor and human rights standards, read our sustainability and responsibly made pages.
Yes. We have representatives from Klean Kanteen living in China who visit our factories regularly. They work as liaisons to ensure all Klean Kanteen products are produced with respect for the environment and that the workers in the factories are safe, protected and paid a living wage. In addition, a rotating group consisting of the owners and various employees visits the factory two to three times a year.
We currently perform regular product testing through third-party, accredited laboratories to meet regulatory requirements and our own high standards for product safety.
Klean Kanteen is and will continue to be one of the safest and most sustainable beverage containers on the market.

It depends on which bottle style you're using. Our Classic and Wide lines are single-walled. If you have a cold drink in them and it's hot out, you're going to have condensation build-up on the bottle.
Our Insulated bottles are made using durable, double-walled construction and vacuum insulation, which has amazing insulating properties. Because they're insulated, these bottles will not have condensation build-up on the outside, regardless of what's inside them or the temperature outside.
The best solution to naturally occurring condensation on Classic and Wide bottles is to put your Klean Kanteen in an insulated sleeve.
If you have a vacuum insulated Kanteen, absolutely! Our high-performance, double-walled, vacuum insulated bottles are designed to function as a thermos, a to-go mug and food storage container and will keep contents hot or cold for up to six hours and iced drinks chilly for up to 24.
We do not recommend using single-walled Klean Kanteen Classic or Wide bottles for hot beverages because you can burn yourself. Warm beverages can be used at your own personal comfort level. They're fine for cold beverages, but unlike the Insulated Kanteen, condensation will form on the outside.
In a pinch, single-walled Classic and Wide bottles (with the Brushed Stainless finish) can be placed on a fire or a stove as long as you take the cap off. Do not do this with a painted bottle, as it will damage the paint.
But it's VERY important that you know what kind of bottle you have because this is absolutely NOT an option with any Insulated Kanteen. Heating a Kanteen Insulated will damage the bottle and voids the one year warranty.
It's pretty easy to tell what kind of bottle you have, even if you've had your bottle so long the logo's worn off. Insulated bottles only come in the wide-mouth design, so if you have a bottle with a long neck and a small rolled lip at the edge, you have a Classic, NOT an Insulated. Insulated bottles also have a separate, extra shiny piece at the bottom and come in different sizes (12oz, 16oz, and 20oz) than the single-walled Wide bottles (12oz, 18oz, 27oz, 40oz and 64oz).
Classic and Wide bottles (in Brushed Stainless finish) are dishwasher safe. We recommend handwashing all painted Kanteens and all Insulated styles.
For daily cleaning, rinse your Kanteen with warm, soapy water and let it drain and dry in your dish rack with the mouth downward so water can drain out.
For thorough cleaning, you can use warm, soapy water and a bottle brush. We also recommend an old-fashioned cleaner: diluted vinegar or water and baking soda.
All the newer Classic Caps (except the Stainless Unibody Bamboo Cap) and all Wide caps are dishwasher safe. The Café Cap is also dishwasher safe and the rotating piece on the top pops out for thorough cleaning.
NOTE: The original Stainless Loop and Flat Caps are not dishwasher safe. If your Classic cap is two separate pieces and has stainless threads with polypropylene on the top, you have the original Classic caps that needs to be handwashed.
Visit our Care & Use page for more information.
Your Klean Kanteen is made from high quality food grade stainless steel that will not retain flavors or smells after you've thoroughly cleaned it. If you've already given it a good scrub with a bottle brush and warm soap water, try mixing a quarter cup of vinegar and 3-4 tablespoons of baking soda in warm water and let it soak in your Kanteen overnight.
Often the problem is in the cap, especially the Café Cap. Make sure you pop your Café Cap apart and really scrub it well, including around the tiny o-ring on the removable part of the cap. You can also soak any cap overnight (except the Stainless Unibody Bamboo Cap) in the same mixture of vinegar and baking soda you use for soaking the bottle.
Visit our Care & Use page for more information.
Make a paste using a little bit of vinegar and baking soda and give it a good scrub. The baking soda is an all-natural abrasive that will help get the stains out. You can also soak it overnight in a mixture of about a quarter cup of vinegar and 3-4 tablespoons of baking soda.
Visit our Care & Use page for more information.
Freezing your Klean Kanteen voids the one-year warranty because the expansion of the water can put so much force on the steel that it causes it to bulge or even split at the weld. Sometimes nothing at all happens. It depends on whether the cap was on, and how much liquid was in the Kanteen.
But you're not the first person to accidentally freeze liquid in your bottle. It's still safe to drink from it, and freezing the bottle does not alter the safety or composition of the food-grade stainless steel in any way.
If the bottom of your bottle has become deformed due to freezing, it's usually pretty easy to pop it back into place. First try putting the mouth of the bottle on a flat surface and pushing on the bottom of the bottle with the palm of your hand.
If that doesn't work, flip it over and put the bottom of the bottle on a hard, completely flat surface. Take the cap off and put a board or a book on top of the opening. Then push straight down onto the bottle using your body weight.
In many cases this will flatten out the bottom of your bottle.
You can also use a rubber mallet, but we DO NOT recommend trying to bang out the dents with a hammer as it tends to cause more damage. If nothing you try works, you can also send it back to us and we'll do our best to repair it for you. If you choose this option, call (800) 767-3173 and ask for the repairs department or email email@example.com.
Klean Kanteens are made of heavy gauge stainless steel and outperform all other metal bottles in independent tests. But they can dent if you drop them. Our one-year warranty covers manufacturer's defects only, not damage caused by using or dropping your bottle.
If you dropped your bottle and dented it, odds are the dent is inward. In some cases you can put a wooden dowel or a wooden kitchen spoon inside the bottle and tap on the other end with a hammer to push the dent out. DO NOT use a metal object to bang the dent outward as the metal can get inside your Kanteen. You can also further damage or even puncture your bottle.
Even if you've dented your bottle, it's still totally safe and free of harmful substances. Because every Klean Kanteen made if 18/8 food-grade stainless steel through and through with no liner on the inside, a dent, no matter how large, will not change the composition of the metal.
Sports caps were originally designed and used with squeezable plastic drinking bottles. Because you cannot squeeze stainless steel, we had to alter the design so that air could get back into the bottle as you drink.
The little white dot on the top of the Sport Cap 2.O is a leak-resistant silicone valve, which allows air back into the bottle so water can flow out. The noise that you hear is air moving through the valve.
Older sport caps do make a whistling noise when used. While the Sport Cap 2.0 is significantly quieter than the old sport caps, it still makes a little bit of noise as air passes through the valve into the bottle. But if your Sport Cap 2.0 is making a loud chirping or whistling noise, the silicone valve may be in the wrong position or may be dirty or clogged.
You can remove the valve and clean it, but it’s very difficult to put it back. Instead, we recommend thoroughly cleaning the inside of the cap with a bottle brush and warm, soapy water and also pushing the little silicone nub on the top of the cap to the side and cleaning around it. You can also rotate the valve to make sure it’s positioned correctly.
Another trick is to loosen the cap just a tiny bit, just make sure it’s still tight enough to keep the bottle from leaking. The silicone vent will work better if the cap is not over-tightened.
If your Sport Cap 2.0 continues to be louder than normal, or if you are not satisfied with the product, please contact our returns and warranty department by calling (800) 767-3173 ext. 319 or by emailing firstname.lastname@example.org

Under normal use, paint on a Klean Kanteen will not flake or chip off. When we developed and tested paint for Klean Kanteen use, safety was our first concern but durability was a close second.
Our paint performs well in lab tests and many of us at Klean Kanteen use painted bottles so we've been putting them to the test in the real world too. Sure, if you drop your Klean Kanteen or jam it into a metal water bottle cage, you can scratch it. It's also possible to scrape off the paint if you try hard enough, just like any other painted surface.
But if your paint is flaking or peeling off, you might have gotten a bottle from a bad batch, which does happen occasionally. If that's the case, it's covered by our warranty and we'll replace it at no cost to you. Check out our Returns & Exchanges page.
To prolong the life of your painted Klean Kanteen, we recommend hand washing it with mild detergent. The Brushed Stainless finish is the best choice for ultimate durability.
