Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

Customers find the thermos keeps drinks cold for up to 1.5 days and appreciate its durability, noting it doesn't break when dropped. Moreover, the bottle is perfect for kids at school, easy to clean, and fits nicely in car cup holders. They consider it better than Hydroflask and worth the money. However, the leak-proof feature receives mixed reviews - while some say it doesn't leak, others report issues with the straw positioning.

- Reviewed in the United States on April 19, 2021Color: Reef BlueVerified PurchaseI have three very active kiddos, 2.5, 7 and 9, that enjoy cold water during activities. The insulated water bottles are wicked for keeping their drinks cold. These water bottles are perfect for them. The handles make it easier for each kiddo to carry the around even for my youngest. They happen to fit in the water bottle pocket of the backpacks we use but you can also attach a carabiner. They fit nicely in our car cup holders which is a huge plus as we encourage the kiddos to be responsible for their own water bottle. We had to go over where the threading was for the cover and remind the kids not to fill above that line because you will overflow when placing the cover on, but we absolutely would buy these again! I don’t think we will need to buy more for our guys though because they are sturdy and easy to keep clean.
We like the color options too. I would like a silicone cover for the bottom of the bottle because my kids will just chuck them at the table or other surface and these things are hefty. The thud is always shocking. Not a big issue though, my guys are just not thoughtful when placing items down.
- Reviewed in the United States on February 3, 2025Color: Reef BlueVerified PurchaseQuality brand tumbler for kids school backpack. Keeps water cold in the Florida heat.
- Reviewed in the United States on June 24, 2025Color: Reef BlueVerified PurchaseMy favorite kids water bottle as a mom of three boys. We've had this water bottle for over three years and it has held up to all of the drops and falls my now 6 year old has put it through. It is leak proof and mold free. It fits neatly in the water bottle pouch of his backpack or down in my tote. He can now even open and refill it on his own. We purchased two more for the little brothers too. 10 out of 10.
- Reviewed in the United States on February 26, 2022Color: Reef BlueVerified PurchaseI have been a big supporter of other brands such as Contigo and the sorts.
I did give 3 stars for leakproof as I bought this cup knowing it was not leakproof but it also doesn’t leak as quick as you would think when laid over.
The Yeti 12 oz cups are the perfect size to dump a small bottle of Gatorade in (fits the entire cup, or a small cup from most fast food chains) and they keep the drink perfectly cold or warm!
I wish I would’ve taken the plunge for my 4 year old son earlier! My daughter who is 18 months old loves her big brothers cup so much that we actually had to buy a pink one for her and they are the cups that both of them use all the time now.
They are durable, easy to clean, comfortable to hold/carry and also super cute and come in a variety of fun colors!
If you’ve been on the fence about spending the few extra dollars on a Yeti for your child or even yourself, here is your sign to buy it right this instance!
- Reviewed in the United States on April 24, 2023Color: Reef BlueVerified PurchaseMy daughter has been using a sippy cup since she was 9 months old (she is now 2). I have spent hundreds (and amassed a huge collection) on sippy cups looking for the "perfect" design and checked all my boxes: easy for her to carry (she is missing her left hand), easy for her to open / close, big enough to hold juice for an entire outing or meal, keeps her juice cold, and the BIG box - doesn't leak!!
This checks every box and I am thrilled! So thrilled with the first one that I bought 2 more and now it's the only thing she drinks out of. It will last practically forever and will grow with her.
I threw out every other cup she had and now we use these exclusively!
We have always been big fans of Yeti products and own several coolers and tumblers but this is by far my favorite Yeti purchase!
- Reviewed in the United States on January 8, 2025Color: Reef BlueVerified PurchaseItem was nicely priced, very good quality. The seller shipped quickly & packaged item safely. Thank you ! 10/10 would recommend.
- Reviewed in the United States on January 22, 2021Color: Reef BlueVerified PurchaseMy toddlers bring these everywhere, use them daily and they are super durable. We love these water bottles since they hold a bit more than other kid bottles, they have a handle so it’s easy for them to carry, and they are stainless steel. My only note would be that they leak if you leave the straw in the open position so I wouldn’t recommend them for kids younger than 3 since they tend not to shut bottles but if your kid can and will close it each time it’s the best one we’ve found and my kids love theirs. We’ve had others with silicone parts and while those didn’t leak when the straw was open mold eventually grows in the tiny parts between the plastic and silicone and it’s dreadful to try and get out. This bottle does not have any of those areas for growth so it makes me feel better and it’s easier to clean.
- Reviewed in the United States on May 16, 2023Color: Reef BlueVerified PurchaseThe handle at the lid of the cup is how my son is able to easily pick this up and hold it to drink out of. He will have one hand on the handle and another on the bottom of the bottle while drinking. It is heavier than a small plastic straw cup he used to drink from. He can easily open and close the straw. Keeps drinks cool. It will leak if the straw is OPEN and it tips over. At his age he is pretty reliable about not purposely spilling his drink. Maybe it’s the “new” factor of this cup or maybe the straw is easier to drink from since it isn’t an “anti-leak” straw like many other toddler cups but I’ve noticed he had been drinking much more water vs usual (something that is an ongoing struggle with him). I know most ppl are probably happy it is 12oz, I wish it was smaller sized 8 oz cup.

5.0 out of 5 stars Bueno pero caro
Color: Reef BlueVerified PurchaseEsta muy lindo, muy resistente, de muy buen tamaño un tanto pesado pero bien, aunque su precio es muy caro, espero y dure mucho tiempo y en realidad no se raspe ni derrame el líquido como promete

5.0 out of 5 stars The best water bottle for toddlers!
Color: Reef BlueVerified PurchaseThe YETI Rambler Kids Bottle is a durable and well-designed water bottle perfect for active kids. Made with stainless steel construction, it’s highly resistant to dents and scratches, ensuring it can handle everyday rough use. I have watched my toddler drop it out of the truck, with no major dents. The picture attached is with 6+ months use!
The Double-Wall Vacuum Insulation keeps drinks cold for hours, which is ideal for school, sports, or outdoor adventures.
The Straw Cap is easy to use, leak-resistant, and simple for kids to open and close. Its dishwasher-safe design makes cleaning hassle-free for parents. While it comes at a higher price point, the YETI Rambler Kids Bottle’s quality and longevity make it a worthwhile investment for families!
Our family loves YETI!

5.0 out of 5 stars Yeti tumbler
Color: Reef BlueVerified PurchaseI absolutely love this Yeti tumbler for my toddler! It’s incredibly durable and holds up to all the dropping and rough handling that comes with little ones. Best of all, it doesn’t leak, which is a lifesaver for keeping messes to a minimum.
The size is perfect for small hands, and it keeps drinks at the right temperature for a long time. It’s easy to clean and built to last, making it worth every penny. Highly recommend for parents looking for a sturdy, leak-proof tumbler for their kids!
