We love this kids’ Yeti Rambler! The designs are adorable, and it’s the perfect size for little hands. My 2-year-old has no trouble holding or using it independently. It also keeps water cold for a long time, which is great when we’re out and about. Pros: * Cute designs * Easy for toddlers to hold and use * Keeps drinks cold for hours * Durable and well made Cons: * None so far Overall, this has been an excellent water bottle for my toddler. It’s easy to use, keeps drinks cold, and I’d definitely buy another one.

I’m so impressed with this kids YETI Rambler Jr.! The quality is exactly what you’d expect from YETI—super durable and built to last. It feels sturdy enough to handle all the drops, tosses, and chaos that come with kids. It keeps drinks cold for hours, which is amazing for school, sports, car rides, or days outside. The size is perfect for little hands, and the straw lid is easy for kids to use without making a huge mess. I also love how easy it is to clean, and the fun color options are a bonus. This has quickly become our go-to cup. Definitely worth the investment and highly recommend for any parent! ⭐⭐⭐⭐⭐

his YETI 12oz kids bottle is incredibly tough and survives endless playground drops without a single dent. The color looks amazing and the paint never chips or peels. When the straw is flipped down, it is perfectly leak-proof—no spills in the backpack at all! Plus, the insulation keeps water ice-cold for the entire day.The only minor issue is the cap. You really need to clean the lids properly by taking the pieces apart, or juice residue can build up in the crevices. Luckily, it is dishwasher safe, so deep cleaning is easy.

Perfect for my son after breaking like 5 other ones from other brands! This is very durable, it does not leak, fits the cup holder and maintains the ice throughout the day

The YETI Rambler Jr. 12 oz Kids Bottle with the straw cap is definitely an investment, but it's one we’re so glad we made! While it’s on the pricier side, its durability and design have proven to be totally worth it. Our toddler is quite the little adventurer, and this bottle has survived countless tosses, drops, and spills without showing signs of damage. Unlike other kids' bottles that break or crack after just a few rough uses, this one stands up to the test. The straw cap is an excellent feature for young kids, making it easy for our toddler to drink from without making a mess. Plus, it’s spill-proof, which is a huge bonus when you’ve got a busy, active child. The bottle is also easy to clean, which is essential for us. We've thrown it in the dishwasher multiple times, and it’s still in great condition. We really appreciate the high-quality build of this bottle. The double-wall vacuum insulation keeps drinks cold for hours, which is perfect for both outdoor play and car trips. Whether it’s a hot summer day or a chilly winter outing, the YETI bottle keeps liquids at the right temperature, making it more convenient and enjoyable for our toddler to stay hydrated. The size is also ideal for little hands. It fits perfectly in our child’s grip, and the compact design makes it easy to throw into a diaper bag or backpack without taking up too much space. I’ll admit, it’s a bit on the expensive side compared to other bottles, but given how tough and well-made it is, I would recommend it to any parent with an active child. The quality and longevity of this product make it a wise investment, and I expect it to last us through many more years of use. If you're looking for a bottle that can withstand the wear and tear of toddler life and still look great, the YETI Rambler Jr. is a fantastic choice! Definitely worth the price for the peace of mind and the reliable performance.

My nephew loves this bottle so much, perfect for tiny hands! It’s easy to carry and keeps drinks cold on a summers day.

Great cup for toddlers 2.5 yrs+ who do drop their cups often so the price is worth it (had one of them for over 2 years)! It’s the perfect size (cup part is 5 3/4”, from the bottom of the cup to top of the handle it is 8.5”), it keeps drinks cold for a while (haven’t tried warm drinks in it yet), it is not easy for kids to unscrew the lid but easy for them to pop the straw open! The inside straw is detachable from the lid to make for easy cleaning in the grooves. It will only leak if the straw on top of the lid is flipped open and the cup is laying down

You get what you pay for. This is the absolute best water bottle. The color is so nice and the build quality is as good as it gets. Easy to clean as well. If you want the best for you or your kids, this is the best option.
