The best drink bottles for kids! Reusable, reliable & leak-proof.
We’ve tried stacks of kids water bottles over the years. Some have broken, others have become too small, and of course, some have gotten lost! But we persevere because we think it’s important that our children’s water bottles are of high quality, and we don’t want to buy disposable bottles for them. Those single-use plastic ones are terrible for the environment and can leach chemicals into the water too.
Click here to go straight to the very best reusable water bottles!
Luckily for you, we have done a lot of research and testing, and have some great recommendations so you can choose the very best water bottle for your children (and yourself!). We are really happy with our particular stainless steel water bottles and have some further tips based on our experiences, too.

Materials to consider for kid’s drink bottles
- We have tried several BPA-free water bottles as well as stainless steel bottles, and we prefer steel ones. They’re unbreakable, which is very important for life with kids! And they don’t stain or taste weird after a while.
- After trying single-walled and double-walled bottles, we prefer the double-walled, or insulated water bottles. They don’t get condensation down the side and the liquid should last a whole day at the correct temperature, in any conditions.
- There are some beautiful glass bottles available now, and some are smaller sizes that could be used for kids. Some reusable baby bottles are also glass, which would be fine for adults to handle, but I don’t think glass would ever be a good choice for children to use themselves. Not even with a protective case! The glass is thick but they’re still breakable, and after a drop or two it’s only a mater of time before they crack.
We haven’t tested them, but did have reusable glass straws that were supposedly very difficult to break. Well, we managed to break EVERY SINGLE glass straw in our house, so guess what we only use now? Yep, stainless steel straws.
- Our kids have had some promotional metal water bottles over the years that come with screw-cap lids. The bottles are usually ok (though always single-walled and often cheaper metal) but screw-cap lids aren’t great for young children. They either can’t get them open by themselves, or they manage to spill the contents from the large opening. Don’t go there!
The very best in kids drink bottles (also for grown-ups!)
I did a lot of research before buying our everyday water bottles several years ago. I knew we would take them travelling but they had to be suited to home use too, and buying good quality stainless-steel bottles is an expensive investment. After using so many brands over the years I knew exactly what we needed. They had to meet these three criteria:
- They had to have a leak-proof design, for obvious reasons when travelling and living with kids!
- They had to be double-walled or insulated stainless steel water bottles, because we dislike having our water heat up on a hot day, and we don’t want condensation dripping in our backpacks or car.
- They had to have minimal parts and no small or fiddly pieces that are difficult to clean or easy to lose while travelling. (Eg. no internal straws)
I found Ecococoon drink bottles checked all of these boxes. They are insulated 18/8 stainless steel, providing excellent protection for our drinks. They are truly leak proof water bottles which feature a one-way valve that only allows the water through when you take a drink, activated by your drinking motion. And they are suitable for home use or as a travel water bottle, with minimal parts to worry about!
We have had our Ecococoons for three years now, and use them in daily life at home as well as all of our travel experiences. They have been refilled at a Rice Farm and Turtle Project in Malaysia, and in Siem Reap and Phnom Penh in Cambodia they were used at their Refill not Landfill stations.
They were also used throughout our Adelaide to Uluru road trip, as well as every flight, bus and train trip we’ve ever taken. And we haven’t had a single spill from them, plus the water has always stayed at a perfect temperature. They are also easy to fill and are a good size to last for a day’s outing.
Here’s our son Dante demonstrating how they work (35 sec):
Benefits of Ecococoon bottles
- Leak-proof: This is their best feature, and we have tested it well! I am confident with using them in the car or plane, next to the bed or computer, and in our backpacks too. They do not leak when being bumped around or carried, and they can’t spill while you’re drinking from them either. The one-way valve is genius!
(If someone strong is very determined and shakes them really hard, the valve will allow some liquid to pass through. But in our experience, this hasn’t happened. In our everyday life and during travelling we have not had one drop come out.)
- Easy for anyone to operate: There’s no need to adjust anything to take a drink from these bottles. Once the cap is off you can drink from them anytime, without the risk of a spill. At home we keep the caps off and our kids have them around all day, ready to use. And they are easy for little hands to hold and operate, even without handles like a sippy cup.
- Temperature control: Ecococoon make the best insulated water bottle I have ever used, and they keep our water cold all day. Even when leaving them in the car in the heat of an Aussie summer, the water stays cold!
They can be used to keep hot drinks hot too, though Ecococoon recommends getting a screw-cap lid for hot drinks instead of the standard mouthpiece.
- Interchangeable Mouthpieces: Their mouthpieces are the same size regardless of the bottle capacity, which makes life easier for grown-ups doing the dishes! No need to waste time matching up lids and bottles.
- Minimal pieces: Ecococoon water bottles only have three pieces, which fully detach and clean easily. I love not having to insert straws and fiddle about with small parts.
And if the lid or mouthpiece gets damaged or lost, you can buy replacements and still use your stainless steel bottle.
Disadvantages of Ecococoon kids stainless steel water bottles
I do have small issues with them, but they are not enough for us to be unhappy with our purchase:
- Width: They are a little bit wider than some cup holders unfortunately: they’re too big for our car’s back seat, but not for our front seat! They do fit in the kid’s backpack holders though, and would be suitable as a school water bottle.
- Weight: They are heavy when full. Being insulated and wide they can be heavy for carrying them around all day.
- Printing: Like most stainless steel bottles, the beautiful designs will scratch off if they’re dropped or dragged along hard surfaces. Ecococoon’s base colour stays on better but also starts to wear after a lot of use.
You can buy a ‘cuddler’ for them, which is a neoprene protective case that also comes with a carry strap. We haven’t got them but they look good if you want to protect your bottle or carry it more easily.
- Detachable caps: We lost a couple of the caps, which is a bit of a pain to keep the mouthpieces clean while we’re out now. The caps fully detach from the mouthpiece which is great for cleaning and interchanging them, but not so great to keep track of them.
Nothing’s perfect I guess though! They’re still our favourite water bottles, and we’ve tried many, many types.
Our size recommendations for Ecococoon
Ecococoon bottles come in three sizes: 350ml, 500ml, and 600ml.
- Allegra is five and she’s had the smallest size since she turned three.
- We recommend the 500ml for children over about six years old.
- For older kids and adults, we recommend the 600ml.
- Dante would be fine with the 500ml at his age (eight) but as we want to keep them forever, we bought him the largest size. It will last him well but is a little heavy for him to carry around all day.
- Due to their weight, I wouldn’t recommend even the smallest Ecococoon for infants. But they’re suitable as a toddler water bottle, and they work beautifully for a warm milk drink as well as cold water.

These water bottle brands are still some of the best stainless steel water bottles on the market. If you can’t find Ecococoon nearby, you might like to try Klean Kanteen or Thermos Funtainer, which are also functional and cool water bottles for kids.
Joss, my friend and fellow sustainable family travel blogger from Little Green Globetrotter, uses the Klean Kanteen range. She has reviewed them for us:
“Klean Kanteen’s insulated range is my family’s go-to for both hot and cold drinks. The stainless steel bottles, which come in a huge range of gorgeous colours and finishes, are vacuüm insulated and make big promises they absolutely can keep! Depending on the size of your bottle, cold drinks stay cold for up to 100 hours (yes, 4 days!) and hot drinks stay hot for up to 14 hours. I can’t say I’ve tried leaving drinks for this long but I can testify to water still tasting refreshingly cold after at least 24 hours in the height of summer, and coffee remaining hot for a full day at work.
The sports, café and kids’ sippy caps are all leak proof and can be put in the dishwasher. They are also easy to disassemble and wash by hand to ensure no mould growth. My 2-year-old started using his Kid Kanteen bottle from about 8 months and has had no trouble grasping and lifting it himself, although the insulated Kid Kanteens are a bit heavier. We preferred his sippy cap to be free-flow so we simply removed the plastic inner and sacrificed it being leakproof, instead opting to also buy a loop cap to seal the bottle for transportation. Now that he’s older and stronger, he can also use the sports cap and is able to pull it open himself; this is definitely a good option for older children.
My son’s bottles have been dropped, knocked and carted around all over the world, and are still holding up perfectly, with only a couple of minor surface scratches. Likewise with our bottles; they’re incredibly sturdy and perfect both for everyday use at work and to take biking, hiking and travelling the world.”

Thermos Funtainer range
These were our kid’s favourites before we found Ecococoon. They are tough, easy for children to use, and their insulation is excellent.
I compared our Thermos kids water bottles once to an expensive insulated brand that I had (not Ecococoon), by filling them at the same time with the same cold water. When I drank from both many hours later, the kids’ water was still very cold, but mine had heated up considerably. After that, I always felt confident putting smoothies or drinks that had to stay cold in their bottles, as I knew they would last all day.
The Funtainers have pop-up straw valves activated by a button, which my kids loved to press. The straws are fine for us which we’re at home, but as mentioned earlier, I didn’t want to take fiddly parts away travelling. Some people worry about the cleanliness of reusable straws, and you do have to be vigilant with them. Careful washing in hot soapy water with a straw brush is how we care for them.
One thing to be aware of with the Funtainers is: if the straw valve is still wet when you insert it into the lid, the valve won’t seal when you screw the lid on. We had a few spills that way before we worked out what was going on. Otherwise, they are leak-proof.
Dante did manage to break his plastic lid, from dropping it many times. You can buy replacement lids and straws for Funtainers though, which is handy!
