- Reviewed in the United States on March 21, 2023Size: 10 OuncesColor: Construction ZoneVerified PurchaseIf you're in search of a reliable and functional water bottle for your little one, the IRON FLASK Kids Water Bottle is worth considering. With its 10 oz capacity, this water bottle is perfect for kids on-the-go, whether they're at school, playing sports, or simply enjoying outdoor activities. Here are some pros and cons to help you make an informed decision:
Pros:
Durability - The IRON FLASK Kids Water Bottle is made from high-quality stainless steel that's resistant to dents, scratches, and drops. This means it can withstand the rough and tumble of daily use and will last for a long time.
Insulation - The double-walled vacuum insulation technology keeps drinks cold for up to 24 hours and hot for up to 12 hours. This feature is especially handy during hot summer days or cold winter mornings.

- Reviewed in the United States on February 9, 2025Size: 10 OuncesColor: Puppy LandVerified PurchaseI bought this to hang on the outside of my carry on. It’s very sturdy and the pattern is not just for kids because happy dogs are for adults too! Perfect size. Lots of people have gigantic refillable bottles for travel on planes, but because I don’t want to have to get up constantly to use the bathrooms, this gives me just enough to hydrate without going overboard.
- Reviewed in the United States on May 1, 2025Size: 10 OuncesColor: Construction ZoneVerified PurchaseDefinitely a good quality little kids water bottle. Aside from my little one still being a little under age to understand how to open this, it was the perfect size for him! Once opened it was way easy for him to handle and walk around with. After filling with ice Ave even leaving in the car for a good amount of time my little one still was able to return to a cold drink after hanging out, given the 90 degrees outside and the inside car temp higher i am quite pleased! The ice was indeed gone but the drink was not warm.
- Reviewed in the United States on April 15, 2025Size: 14 OzColor: RoadtripVerified PurchaseGreat for my toddler. I mean he’s still learning to use it but it holds up well for a kid that drops stuff a lot and also just wants to chew on it half the time. Super cute, affordable, and seems well made so far!
- Reviewed in the United States on February 21, 2025Size: 10 OuncesColor: Puppy LandVerified PurchaseI bought this small steel sipper for my 2-year-old, and it’s been amazing. It’s really sturdy and has survived quite a few drops without any dents or damage. I love that it’s BPA-free and made of safe materials for my little one. It’s also really easy to clean. My little one loves the cute dog design.
The only downside is that it’s a bit heavier than plastic sippers, but my toddler is getting used to it. Overall, this is an excellent buy, and I would highly recommend it to other parents looking for a reliable, eco-friendly drinking solution.
- Reviewed in the United States on March 1, 2022Size: 14 OzColor: Space HeroesVerified PurchaseI'm giving these water bottles 5 stars because they are the best I have found for my 3 rough and tumble boys. I had a plain colored one first. After the first drop the color chipped and bottle dented (that was on concrete). That being said it is still in use over a year later with no issues. I somewhat recently purchased 3 with design. Those have also been dropped a handful of times and have yet to chip or dent. The one thing I noticed with the ones with design I hadn't with the plain colored one is if they are not closed (mouthpiece shut) they will leak. My kids are 2, 3 and 5. The 5 year old will shut the mouth piece. The 2 and 3 year old cannot be counted on to do as much and the water bottle has then leaked in bags/backpacks, and their beds. These come with extra straws, which is nice and the straws seem to stay in place even when the water bottle is dropped. Liquids seem to stay cold/ice is still in there after a day at school. I found in summer and outside the ice doesn't last long.
- Reviewed in the United States on October 13, 2024Size: 10 OuncesColor: Ocean AmigosVerified PurchaseDownfall - yes it will leak when tipped upside down. Positive - it holds ice better than my Yeti, easy to clean, great cup. Would buy again over a Yeti!
