    Love it! I got a replacement cap because the original one accidentally fell on the heating element of the dishwasher and melted. We use polar bottles daily for school lunches and sporting events. We love them because they are so durable. We got our first one almost 4 years ago and it is still going strong.

    Thanks so much for the bottle caps! I have had your polar bottles since the beginning.
    I own 4 old large bottles, one old half, and 2 new regular. I keep purchasing more so that everyone in the family that rides a bike has bottles. This is a great customer service and environmental friendly business model that other companies need to follow.

    Thanks for replacing my lost caps – I’ve been using my three Polar insulated bottles for years and they never let me down – would have felt terrible to pitch them just because of my carelessness.

    I hate to be critical of something provided for free.

    First, the free replacement caps are a perfect fit, and seal without leaks every time. And the free replacement program cannot be beat and is MUCH appreciated.

    My only issue is the rubber stoppers fit too tight. When riding my bike, I pull the stopper open with my teeth. It takes considerable force to pull it open. I think this is the major cause the stoppers break in the first place. I am certain if the stoppers were just a fraction of a millimeter smaller in diameter (or the cap hole a fraction of a millimeter larger), the stoppers would still seal properly, but be easier to slide open and close.

    This would make it easier on your customers, but I feel would mean fewer free replacements you would need to provide. A Win Win. I would much rather see a resizing than you do away with the free replacement program.

    We have 6 polar bottles, 2 of them needed new lids after heavy use by my kids during sports and daily use at school. The rest of the bottle was still in perfect shape so I was thrilled to find I could get new lids for the nominal cost of shipping. Thank you!! Great customer service perk!!

    We’re an active family of 4 and go through countless water bottles a week. With repeated use, the caps start to wear or if you have a dog that enjoys chewing on them, like ours you need to get them replaced more often than you’d like. I love that Polar offers a free replacement AND the caps are so easy to clean compared to the other companies out there.

    Appreciate the lifetime guarantee!

    Did you know Polar Bottles are great for portable margaritas whilst camping and hitting the beach or after making camp with a lime Gatorade and ice after a long bicycle ride?

    At least that’s what my friends told me! 😉

    WOW! I have a dozen of these bottles. One in each room and an exchange of them for travel daily or long term. After MANY years of use, my husband broke one of the caps. A search to try to buy a new cap was rewarded with learning that Polar not only make THE BEST bottles, but that their OUTSTANDING SERVICE does not end at the initial purchase!! They’ll send you a replacement cap for Free. AMAZING.
    THANKS!!!!!

    THANK YOU for offering life time replacement on caps. That is huge in my house. Great caps, someone here just likes to use their teeth on them too much. 😉 Polar caps are much easier to clean than some others, as well.

    Great company to warrant all caps @ N.C. I have both the old style and new style bottles, and with many riding miles, cleaning, and drinking, the caps wear out. Kudos to Polar for maximizing the overall life of the product. Definitely a fan for life. This bottle is the only bottle I have found the keeps the water “cold” on those hot days(pre-pack with ice.)

    My Polar bottle saw me through many RAGBRAIs, but the cap finally gave up. Was so surprised to find that I could get a free replacement. So happy, I ordered a new bottle for a friend. Perfect fit – love the loop, too.

    Thank you.

    Polar bottles are awesome – they do what they say – which is keep your water COLD.

    And I will or use any other company for sports bottles – this company is making a difference in the world by reducing waste by providing replacement caps – this is how we should be expecting companies to behave in our country – responsibly.

    Week done Polar!

    It’s hard to be critical of something received for free. But I do have a problem with my two free replacement sport caps. The black rubber stopper valves fit too snugly. I use my bottles while riding my bicycle. That means, it is a one-handed operation. So I grab the stopper valve with my teeth and pull. I have to pull pretty hard to open the valve. Then I press the valve against my front teeth to close it, and having to press pretty hard.

    My friend has two fake teeth fears it requires too much force on her teeth, causing them to come loose. So she has to stop riding just to get a drink. 🙁

    My fear is this will cause the rubber stopper valve to break before one riding season has passed.

    Otherwise, 10 Stars for the free replacement program that helps keep plastics out of our landfills.

    I cycle a few thousand miles a year and always carry at least one Polar Bottle. I have had mine for a number of years and use the bottles a lot. The valve on the cap works well and lasts a long time but like any moving part, gets worn over time. The Polar Bottle guarantee to replace worn caps helps bottle owners and the environment. I will always use Polar Bottles for my sports activities!

    We have two sets off Polar bottles that we have been using for years. Love that
    the bottles are light , well insulated to keep water cold for outdoor activities. We Never have to buy those throw away water bottles!
    The lids do tend to show a bit of wear over time, so am very thankful that the company
    stands behind their product and provides free replacement lids!

    Everyone in the family has at least one polar bottle, so the black tips hardly ever break but after several years it does make this free replacement a definite plus. It’s a real plus to be able to twist the black tip 90 degrees to remove for cleaning periodically.

    Its hard to believe that customer service as good as this still exists. We have three Polar water bottles . We lost one cap and damaged another. These bottles have had a hard life and have really stood the test of time and are by far our favorites.
    We got sent two replacements for the cost of postage which arrived very promptly from 5000 miles away. It doesn’t get much better than that.
    Very pleasant experience to buy from someone who want to deliver you maximum value and satisfaction and I will be a life long customer of their products with service like this.

    Well, after using my Polar water bottle for well over 12 years, my cap wouldn’t stay open or closed when I needed it to. Getting a replacement top was super easy, and super fast!! I’m certainly very appreciative of Polar not charging for a replacement cap, and only charging shipping!! Highly recommended!!

    I have had two bottles for about 8 years now and the valves had started to deteriorate. I was really happy to be able to replace just the cap and not have to throw away the bottle. Even better that I only had to pay a small shipping fee (even to Hawaii). Customer service was quick to respond and help me determine that I needed a new cap vs the old style.
    Thank you!

    Offering free replacement caps is a great service, and much appreciated! I recently had to replace two. It was quick and easy, and I only had to pay a modest amount for shipping. It’s a pleasure doing business with a company that not only offers great products, but also makes it so easy to continue using them for a long period of time.

    I own several Polar bottles and love that they are made well, cost effective and have a lifetime warranty. I just found out about the free cap and carrying loop replacement program and feel that paying for shipping for these is more than fair. The replacement program tells me Polar Bottles is committed to the environment and that makes me a lifetime supporter of the business. Thank you Polar Bottles!

    I’ve had my Polar Bottle for 17 years and when I found the valve had started to disintegrate I thought that I would have to junk it. The I decided to google ‘polar bottle’ and to my surprise found that it had a lifetime warranty. Online ordering was easy (and yes there is a shipping fee) and I received a new cap only a few days later.
    Excellent service for an excellent product.

      Thanks for the feedback and support.

Frequently Asked Questions

The Polar Bottle Sport cap is manufactured by our supplier in Denver.  We assemble the cap on to bottles, and ship it from our Boulder, CO headquarters.

Polar Bottle products are made from PP, LDPE, HDPE, and Tritan™ plastics, which are free of harmful chemicals like BPA and Phthalates. To the furthest extent of current scientific knowledge, none of these plastics contain harmful chemicals that may leach into the liquid contained in the bottle. The well-being of our customers is of the highest priority to our company and plastic safety is an issue we take very seriously.

Polar Bottle products have always been BPA and Phthalate Free.


Yes, Polar Bottle caps are dishwasher and freezer safe.

Yes, all drinking valves on Polar Bottle caps are removable for easy cleaning. To remove the valve, first pull up on the valve until the cap is fully open. Then, add a little pressure to pinch the valve so that you can turn it to the left until the dots on the valve and cap line up. Once the dots line up, simply pull up to remove the valve fully from the cap.

To reinsert the valve, line up the dots again, push the valve fully closed, then twist right to lock in place.


The old style cap fits only the original Polar Bottle, which had a screen printed logo (rather than a design printed on the foil liner), as well as a slightly different shape. We made this change in 2004. All 12oz, 20oz and 24oz made since then are fitted with the standard sport cap.
