## Customer Reviews

### ⭐⭐⭐⭐⭐ Great water bottle for little kids
*by J***R on July 2, 2025*

I’m now on my second bottle, and I’m impressed with its simple, durable design. Unlike other bottles with lots of silicone components, this one only has silicone where it sits in the base. The strew is remarkably sturdy and withstands heavy chewing without breaking down. What I love most is how easy it is to clean - just three parts to wash, the straw opens up completely so you can scrub out any food particles that get stuck inside.The insulation is excellent too. It keeps drinks cold for hours, even when I’ve accidentally left it in a hot car. The bottle handles drops like a champ, and it’s perfectly sized for my 3-year old to carry around independently. Overall, it's a well-designed, practical bottle opener hat actually delivers what it promises.

### ⭐⭐⭐⭐⭐ Great 20 oz water bottle for kids
*by J***O on July 18, 2024*

The media could not be loaded. The Hydro Flask 20 oz Water Bottle is an outstanding hydration companion that lives up to its reputation for quality and performance.#### Design and Build QualityThe Hydro Flask 20 oz Water Bottle features a sleek, modern design available in a variety of vibrant colors. The build quality is exceptional, made from durable stainless steel that feels sturdy and robust in hand. The powder-coated finish adds a premium feel and provides a good grip, even when the bottle is wet.#### Insulation PerformanceOne of the standout features of the Hydro Flask is its excellent insulation. Utilizing double-wall vacuum insulation technology, this bottle keeps drinks cold for up to 24 hours and hot for up to 12 hours. I’ve tested it with both hot coffee and iced water, and it performed admirably, keeping my beverages at the desired temperature for extended periods.#### UsabilityThe 20 oz size is perfect for daily use, whether at the gym, office, or on the go. It fits comfortably in most car cup holders and backpack side pockets. The wide mouth makes it easy to fill, pour, and clean, and it can accommodate ice cubes for an extra chill. The Flex Cap is a convenient addition, featuring a flexible strap that makes it easy to carry around.#### DurabilityAfter several months of use, the Hydro Flask shows minimal signs of wear. It has withstood drops and knocks without denting or scratching significantly, maintaining its aesthetic and functional integrity.#### MaintenanceCleaning the Hydro Flask is straightforward. It’s dishwasher safe, but I prefer hand-washing it to maintain the finish. The wide mouth allows for easy access to the interior, ensuring a thorough clean every time.#### Pros- Excellent insulation keeps drinks cold for 24 hours and hot for 12 hours.- Durable, high-quality stainless steel construction.- Sleek, attractive design with a variety of color options.- Wide mouth for easy filling, pouring, and cleaning.- Convenient Flex Cap for easy carrying.#### Cons- Slightly heavier compared to plastic bottles.- Premium price point, but worth the investment for quality.#### Final ThoughtsThe Hydro Flask 20 oz Water Bottle is a top-tier choice for anyone looking to keep their beverages at the perfect temperature while on the move. Its exceptional insulation, robust build quality, and stylish design make it a reliable and attractive addition to your daily routine. Despite being a bit pricier than other options, the durability and performance of this bottle justify the investment. Highly recommended for both everyday use and outdoor adventures!

### ⭐⭐⭐⭐⭐ Durable and functional
*by J***I on January 23, 2025*

This green Hydro Flask Jr. water bottle has been a total game-changer for my son! Ever since he got it, he's been chugging water like it's going out of style. He loves the color, the size is perfect for his little hands, and he feels so "grown-up" carrying it around.Before, getting him to drink enough water at school was like pulling teeth, but now he proudly takes his Hydro Flask everywhere. It keeps his water cold all day long, which is a huge plus, and it's super durable – it's already survived a few drops with no dents or scratches.Honestly, I can't believe the value for the price. This thing is built to last, and it's made staying hydrated way more fun for my son. If you're looking for a water bottle that's both kid-friendly and high-quality, look no further!
