Doesn't Spill, Keeps things cool, Easy to clean

CarrieOctober 9, 2024✓ Verified purchase

I love these water bottles. I have purchased two sets so far (one for each kid). They are easy for my kids to carry and open the spout to drink on their own. The lid seals tightly so if they are knocked over there are no worries about spills or leaks unless the spout is open then you may get a little water on whatever surface. They don't come loose in backpacks, so you don't have to worry about wet homework pages or library books! My kids are outdoors a ton and these bottles keep the contents cool for several hours making them great for summer outdoor activities. They also can take a beating, they've been dropped on rocks and rolled down driveways, chucked off playground equipment for me to catch (which sadly is not a skill I possess), and still hold up. And for those who are busy, these bottles are SO easy to clean, there are no fiddly bits you need to worry about to search for mold, and everything is easily viewable and washable. My kids put vinyl stickers on their bottles so I don't put them in the dishwasher and even handwashing, it's a quick minute to get them shining. These are my go-to water bottles for kids. As for the kids' opinions, they love the colors and that they can open the spout easily. And they love that the vinyl stickers adhere well and don't fall off. Read more

Perfect for Active Kids and Busy Parents!

Lisa SApril 26, 2025✓ Verified purchase

I absolutely love these ThermoFlask Kids Bottles! The size is just right for little hands, and the straw lid makes it super easy for my kids to stay hydrated throughout the day. The water bottles are lightweight but incredibly sturdy — no dents or leaks, even after a few (inevitable!) drops. The insulation is amazing too: water stays cold for hours, even during hot afternoon playdates. The colors are vibrant and fun, and the two-pack option is a total win for families with more than one kid (or for keeping a backup ready!). Highly recommend for anyone looking for a durable, kid-friendly water bottle that actually lives up to its promises! Read more

Durable and easy to clean!

NoreenNovember 9, 2025✓ Verified purchase

I bought these for my boys (8 and 6 YO) and they are perfect. Durable, keep the water cold and hold enough so we're not always refilling. I really like the rubber boot on the bottom of the water bottle to help from sliding and denting when it's dropped. Also, they are so easy to clean! Read more

Get them!!!!

bc whySeptember 20, 2025✓ Verified purchase

I have two boys under the age of five and they are rough on everything they touch but these ThermoFlask kids bottles hold up like champs. They get dropped, tossed in the car, and taken on every adventure and they still look and work like new. The straw lid is easy for little hands to flip open and drink from and it never leaks in my bag. The bottles keep their water cold all day even in the summer heat and the size is perfect for small kids to carry themselves. After months of daily use and more than a few tumbles these bottles have proven they can handle anything my boys throw at them. I recommend them to any parent who needs a durable and reliable kids bottle. Read more

Very durable and well worth the price.

tyler keetchMay 29, 2025✓ Verified purchase

We've got two boys that are proficient at destruction (including multiple water bottles). We bought these a few months ago, trying to find something more durable, and so far, these bottles have been perfect. They're a bit bigger than other "kid" water bottles we've purchased, easy to clean, and work as they are supposed to. The biggest plus, specifically for my littles, is the fact that the straw is solid. They both will sit and chew on the straw on occasion, and they've ruined multiple water bottles because of it. We had tried other water bottles with solid straws, but they always managed to break those as well (usually by dropping, which happens very frequently with both of them). These water bottles have dealt with being chewed on, dropped onto concrete, and knocked into things, and have lasted longer than pretty much anything else we've gotten them. We'll likely buy these again should my boys ever need replacements. Read more

Great Value and Durability for Toddlers – Perfect Water Bottles for Active Kids!

Jonathan LeeOctober 26, 2025✓ Verified purchase

I purchased the ThermoFlask Kids Bottle with Straw Lid set for my toddler, and I’m really impressed with how well it’s held up. The set comes with two bottles, making it a great value for the price, and the bright, vibrant colors are an added bonus. My toddler absolutely loves the fun colors, and it’s easy for him to identify his bottle when he’s at school or daycare. The durability of these bottles is a huge plus. As any parent knows, toddlers can be a bit rough on their belongings, and my son is no exception. He’s been known to throw his bottle around, drop it on the floor, and even bang it against things, but these bottles have stood the test of time. The stainless steel material is tough and resistant to dents and scratches, making it perfect for active kids. Another thing I really appreciate is that these bottles are dishwasher-safe. This makes cleaning them so much easier, especially since my toddler tends to leave a bit of a mess with his drinks. The straw lid is also easy to use and spill-proof, which is a must when dealing with young kids. No more worrying about spills in the car or at playdates! The insulation works well to keep drinks cool throughout the day, and the double-wall construction helps maintain the temperature for a decent amount of time. While it’s not as long-lasting as some more expensive options, it still does the job for daily use. Overall, I’m very happy with these bottles and would highly recommend them to anyone with an active toddler or young child. The reasonable price, durability, and easy-to-use design make it a great buy for parents looking for a practical and reliable water bottle for their little one. Read more

Good quality water bottles

AmazonCustomer100December 9, 2025✓ Verified purchase

The bottles hold hot and cold water for a considerable time. I avoid the straw when the bottle is holding hot liquid. The colors are bright. The grip is super helpful to protect the bottle from dents. Read more
