This small kids cup is perfect for my son for his lunch. I haven't seen any leakage so far. It came with 2 inner straws which I appreciate since these usually get lost in the dishwasher. It holds 12 oz of fluid and ice didn't melt too fast. I didn't notice a smell to it when it came. The design is very elegant and flawless. I'm extremely happy with my purchase of this cup. It is heavy duty and I see it lasting a really long time. My son loves it! I got the brown and it goes with everything. Fits in the side pocket of my bag and it's short so it stays in. So far we love this cup. ... show more

    • Durable and Reliable, Perfect for Toddlers!
Color: Beekeeper

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. ... show more

    • Perfect for toddler!
Color: Lowcountry Peach
Great stainless steel water bottle for toddler! My daughter wants to be just like mom with a water bottle and this one is perfect! It’s durable for all the time it’s dropped and the color remains vibrant. It holds a lot more water than i expected, I would even use it myself some days. The ice doesn’t melt all day long so the water stays nice and cold. We will definitely have this water bottle for a long time! ... show more

    • Cup that will last!
Color: Rescue Red
This cup has been dropped and threw plenty yet still it holds up great! It keeps things cold. Dose not spill and they have so many designs. We have lots of these cups. Also it’s a hard durable cup but does not hurt child teeth.

    • Built like a tank, perfect for active kids (but a bit heavy)
Color: Big Sky Blue
We’ve gone through a lot of kids’ water bottles over the years, and the YETI Rambler Jr. is hands-down the toughest one we’ve owned. My kid has dropped it on pavement, tossed it in the car, and left it rolling around in a backpack, and it still looks and works like new. The insulation is top-tier: it keeps water ice-cold for hours, even on hot days at the park. The straw lid is genuinely leak-resistant when closed, which gives me peace of mind. (It’ll dribble a bit if left open and tipped, but that’s expected.) I also appreciate that it’s super easy to clean, dishwasher safe, and the straw disassembles without much fuss. The colors are vibrant and kid-friendly, and the handle makes it easy for little hands to carry. A couple of things to note: -> It’s heavier than a typical plastic bottle—something to consider if your kiddo prefers super lightweight gear. -> The straw has popped out a couple of times when refilling, but it’s easy to snap back in. Overall, it’s a great choice if you want a bottle that can survive serious kid use and still keep drinks cold all day. Worth the price for the quality and durability. Still need to keep an eye on the nooks and crannies for mild accumulation so I’d wash it every few days, maybe more in the summer. Easy enough to disassemble and clean though Would definitely buy again (and probably will once my younger one is old enough for one too). Update: make sure to check the interior of the cap unit for mold accumulation. Definitely think this should be washed multiple times per week. ... show more
