Parents Swear By This “Magic” Leak-Proof Thermos® With 40,000 Perfect Reviews on Amazon

I’m a parent to two kids, which means in their combined four years and nine months on earth, I’ve purchased approximately 37 reusable water bottles. Keep in mind that kids don’t use water bottles until they’re about 1.5-years-old, so that should provide a clearer picture of how difficult it is to find a kid-friendly water bottle that doesn’t leak, easily break or start to smell within a week. After speaking to other frustrated parents, reading countless reviews, and anxiously waiting by the door for my Amazon Prime boxes to arrive, I finally found a water bottle that my kids and I love — the Thermos® Funtainer® bottle.

The reusable water bottle market is pretty saturated (water pun!) with options, and not all of them are good. Heck, a lot of them barely qualify as mediocre. Thankfully, I’ve found the Thermos® Funtainer® bottle, which lives up to its name. No one has fun when water bottles leak, and as a mom and product reviewer, I can verify that this is the leak-proof water bottle you’ve been looking for.

I’m not the only one who’s obsessed. Amazon shoppers describe this water bottle as “magical,” and it’s earned a rare 4.8-star rating even after more than 41,000 reviews.

Thermos® Funtainer® Bottle: Why I Love It

Available in 12- and 16-ounce sizes, the Thermos® Funtainer® bottle has a lot going for it. It has a stainless steel design that doesn’t hold odors, making it an excellent option for milk, juice, or smoothies. The vacuum-sealed design keeps drinks cold for up to 12 hours and has a wide mouth opening that makes it easy to add ice. The Thermos® Funtainer® bottle is highly durable, another big plus for kids.

The push-button lid opener is easy for kids to use, and the built-in handle is perfect for their small hands. I also like that it has a lid over the pop-up straw, helping to keep germs away. If your child is a biter like mine (only straws, thankfully), Thermos® sells straw replacements that are easy to swap out.

The Thermos® Funtainer® bottle is dishwasher safe and available in every color possible. Thermos® has a huge lineup of character choices because, let’s be real: If the Funtainer® isn’t available in Cocomelon/Batman/Peppa Pig/Frozen/whatever your child is into this month, all the other features are a moot point.
