These yetis are stainless steel, double insulated, customizable in color, and are 12 oz bottles. They hold anything liquid honestly. But we mainly use them for water or electrolyte drinks like Gatorade etc. or liquid iv when needed. They are leakproof when they’re fully closed obviously. The mouth part folds out and is like the little almost rectangular sport drinks mouth piece if that makes sense. (Almost like what an inhaler mouth piece looks like?) hopefully that’s making since. When you’re finished drinking you just fold it back over and it’s sealed so there’s no struggle to open for my kids with pulling straight towards their faces and busting their lips etc. yessss my kids are accident prone 😂🤷🏼‍♀️.

Warranties available with yeti products, you can customize colors and they’re dishwasher safe! Both pieces. So mama is happy also! 10/10 recommend for your kids and little ones that love to be outdoors or just love to get their water in or anything of the sort. Easy to track liquid intake with this also. ❤️

This water bottle is so awesome. I purchased it for my son to use for school and it keeps his drink cold all day. I was worried he would be drinking warm liquid but this does not disappoint. It is a little heavy but definitely durable too as it has been dropped quite a few times. His favourite colour is red so awesome to find a bright red bottle too! I love Yeti products and they do last. It came with an extra straw too! I highly recommend and can’t wait to add more yeti products to my household!

I cannot get over the QUALITY!!!!! I am a diehard Brumate fan. I own every one you can possibly think of. I actually have a cabinet in my kitchen dedicated to only brumates. When it came time to back to school shop, I decided to make my kids their own lunches rather get them free lunch. I knew I needed to find them a cup that would have ice cold water last all day. I tried the zak brands from Walmart & many other insulated cups. My brumates worked but not until lunch time. I finally caved & got a Yeti Rambler JR & I can’t emphasize enough how amazing this cup is! Not only is the quality incredibly clean, but it is now Saturday night & there is still ice from my daughters cup I packed for school Friday morning at 5 am when I left for work.

Can’t wait to order this for my third child!
22 April 2022

We’ve had our jr ramblers going on three years now. My son has only used his for water and Gatorade and we clean the spouts by running a pipe cleaner straw-cleaning brush we bought from Amazon down the spout and straw. You can soak them in hot soapy water and rinse well to make sure all of the small parts are clean. However, my daughters school fills hers with milk every day, she’s three and has used hers since she was one. The milk can create a little build up around the spout if not washed right away and soaked, but my sons never has any issues like hers as far as cleaning right up. They come with an extra straw which is awesome. We customized both cups with monogram on one side and first/last name on the other. They’ve taken them to school every day since we got ... MoreWe’ve had our jr ramblers going on three years now.

They come with an extra straw which is awesome. We customized both cups with monogram on one side and first/last name on the other. They’ve taken them to school every day since we got them. They do scratch if you bang them around on hard surfaces but I would expect that with every cup. Overall durability is really great. For my daughter when she was younger we looped a strap through the handle and into the stroller straps in case she dropped it. The handle is genius. The cup keeps liquids cold for crazy amounts of time. I put ice water in them the night before school and the water stays cold through school hours the next day. Also have taken them on multiple beach vacations and they are great for a hot day out playing in the sun, water remained cold/cool for hours. I will probably end up replacing my daughters as one of her birthday gifts in a few months just because of the milk situation and it being a little hard to clean out, but I forget that there’s milk in it occasionally and it sits in it so partially my fault. I cannot wait to get one for my smallest child’s first birthday. It says 3+ but a one year old can definitely use these!! So worth the price point. Customize it to avoid tempting anyone to steal it or to keep it from getting lost. I wrote my phone number on the bottom with a sharpie as well. Don’t hesitate just buy it. I spend $40 in coffee and fast food in a week, these have lasted for years and such a convenience to keep my kids drink cool so definitely don’t have a problem with the price. My photos were taken over the course of two years. They love their cups. Yeti babies for life lol

Expected better from Yeti
16 November 2021

We bought one of these for our baby. He started using it around 7 months ago when we started training him with self drinking. The bottle itself will last forever, but the straw lid is a major fail. It leaks ALOT even when the spout is closed. After constant opening and closing the spout has worn down the plastic where it rests in the lid causing little pieces of plastic to come off. It has hidden spots that hold residual liquids and molds. Between those, it's not a very safe product for children, let alone anyone. We are thinking we'll either replace with a hot shot lid or a chug cap, rather than another straw lid. Those seem to have less hidden spots to clean and should hopefully stay intact. In saying that, I would be more inclined to just purchase a hot shot if ... MoreWe bought one of these for our baby.

Good but not great
27 February 2023

I agree with the reviews about mold. The cap is very hard to clean. What’s also annoying about this cup (that has been mentioned as well) is that there are no replacement parts. So if you need a new gasket seal or the lid breaks, you have to buy a whole new cup rather than just a replacement part. People are complaining a lot about the handles breaking after months, a year but they are after all plastic. They’re pretty strong for what they are and decently made for kids, even toddlers. Just offer replacement parts Yeti.

Great thermos but..
14 March 2023

I bought this for my six year old for both sports and for school and had it monogrammed with his name. It works great for sports, play dates, or playing in the yard but it’s not the best for school or day trips. The 12oz size is not enough water during the day since that is all he drinks. We had to send in an additional bottle of water so he could refill it. It got to be too much so we just use a larger bottle for school.Unfortunately, the next size Yeti thermos does not have a straw top, it’s a chug top, and that does not work. I wish Yeti had a straw thermos for kids that held more than 12oz since that is not a lot of water for a full school day for my first grader, never mind older kids.I also wish the tumbler held up a bit better - boys are tough and toss ... MoreI bought this for my six year old for both sports and for school and had it monogrammed with his name.

A few weeks in it was already heavily dented and the color was chipping off. I had high hopes for this since we are a Yeti family and we have so many of their products and we love them. For the price we expected a bit more quality to hold up to tough and tumble boys and I wish there was a larger size with a straw top.

Keeps drinks cold, easy to cart around.
27 January 2023

I bought each of my kids this cup for Christmas last year to place in stockings. I can say my kids are rough on everything and two take it to school everyday. The handles a year later are still attached with no cracking. And no mold what so ever. The mold cases to me seem to human error. You can’t let these sit for days on end with water in them and not expect mold. Also after being ran through the dish washer (I detach the straw) I let them completely dry out before assembling and placing into my cupboards. Anything put away wet in a dark area with a straw would mold. These are in best shape a year later. I just bought more for Valentine’s Day gifts for them.

No Engraving Offered on pink or purple cups!
3 September 2023

Absolutely love the bottle. The biggest issue I have is the inability to have custom engraving! I bought these same yeti bottles in blue and yellow over the last three years and both were custom engraved with my boy's names but the colors my little girl liked weren't available with custom engraving. She was extremely upset to find out that her cup didn't have her name on it like her brothers do! Local engraving shops are quoting over $100 to engrave it! I'm going to end up paying it to make her happy but I shouldn't have to. Yeti should offercustom engraving on all colors or not offer it at all! I will not be buying another Yeti product after this!

Poor design for children
24 January 2023

This cup is hard to clean. Gump and bacteria form easy in the crevasses on the top. It's hard to clean it, even when I use cup scrubbers. A q-tip is the only small items that can get in there. My daughter's reaction "I've been drinking dirt?!"This is designed for children. Children rarely keep their bottles and cups upright. And as soon as they put it in their backpack or in the car, or it falls over, water spills everywhere. Such a poor design. I do not recommend for this alone.
