Easy to Use and Spill-Proof

ChelseySeptember 22, 2025

This Thermos Funtainer water bottle is excellent! It keeps drinks cold for hours, the design is colorful and fun, and the flip-top lid is easy for kids to use without spilling. It’s durable, has held up through drops and daily use, and cleans easily. My child loves taking it to school and activities, and it’s become their go-to bottle. Highly recommend for parents looking for a reliable, kid-friendly water bottle. Read more

Awesome kids water bottle

LailahSeptember 8, 2025

We have at least a dozen water bottles and this is probably my favorite to use for my kiddo and is the one we bring to school. It has all the features I was looking for: 1) Perfect size for a toddler to early grade school aged child, and fits small hands; 2) Made of stainless steel, sturdy yet not heavy for a toddler to carry; 3) Drinking spout is made of silicone, not plastic; 4) The best feature is that the lid closes over the spout and pops open with the touch of a button, ensuring that the mouthpiece keeps clean and covered when not in use, and your hand doesn’t have to touch it either. For hygiene reasons the lid was a really important design feature to us and was something I specifically looked for in a kids water bottle: that the mouthpiece is not exposed, the lid can be opened by a young child without effort and is attached to the bottle so won’t get lost; 5) Easy to clean and the silicone part pops off and on easily. The seal works well and the bottle has not leaked so far; 6) Keeps beverages cool or hot/warm for a good while. I haven’t tested how long, but for our purposes it’s fine for getting through a school day (not looking for rugged outback multi-day peak performance functionality here); 6) Also nice that they come in many colors and designs! It was surprisingly uncommon to find a water bottle that fit all these criteria, so I was really happy to come across this Thermos bottle that fit the bill! We’ve had ours for almost a year now and bring it to school daily, and it’s still working perfectly. Read more

Children absolutely love them

Ashley CrosslandDecember 19, 2025

My children love these bottles for water! One child has had this type of bottle for almost a year and absolutely enjoys it! My other children wanted one too so they all got these water bottles! Great quality. Easy to clean, stays cold for a while. Bearly any leaking which is great when having children. Its a nice size so they arnt having to fill them up often but not so long the water gets nasty. The bottles are easy to hold onto and carry around! Read more

An overall good water bottle

Vickie NataleOctober 8, 2025

I got the Thermos FUNtainer Water Bottle for my kid, and overall, we liked it. The designs are cute and my kid loved using it right away. The straw and push-button lid are really easy for little hands, and it keeps drinks cold for hour which is great for school or the park. It’s also very easy to clean. Unfortunately mine did break after a few months. I was hoping it would survive more drops, but it didn’t. It’s still a really good water bottle. The outside doesn’t get sweaty, and my kid actually drinks more water because of it. I would definetly buy it again. Read more

Just get it

Angela NottinghamJune 14, 2024

I picked up a Thermos Brand Bluey cup at Target at random. Ok, so it was on an end cap and my son wanted it so I said ok. I liked it so much I bought this one here. First of all, before I was using other brands for his water bottle at school. Sippy cups, NUK brand, that one made from recycled plastic, anything. Usually plastic and typically see through. That stops NOW (for him taking to school, I'm not throwing the others out---yet). First of all, I forgot what made a Thermos great: the insulation. This kid will have his water bottle with ice full at night, and still have ice in the morning. I know when he goes to school his water will stay COLD (it isn't for hot drinks). Second of all, it is durable. Toddler durable. Toddler winging it across a parking lot as they are swinging around telling you a story about Paw-Patrol durable. Sure there may be some surface scrapes, but deep down it's ok. And so are you. This thing is so easy to clean in a dishwasher or by hand. Some sippy cups it feels like you are a EOD expert taking apart and assembling the pieces. Not this guy, pop off the lid, pop off the straw, pop off the mouth piece and clean. Leak proof? Pretty much so, unless you don't screw it on properly. If the lid/mouthpiece is open, yea it leaks, but so do most things when the lids are open. Am I worried about lingering odors? My kid loves water. Like, legit, it's his favorite. We only use this for water so there are no odors. Am I worried about his orthodontic growth due to the impact sippy cups have on his forming teeth? No, is this a new thing? I just want my kid hydrated and not chugging sugar all day. Does it hurt when you drop it on your toe? Oh, you betcha. Will I be buying more? Yes, he has already stated he wanted a space one. Read more
