    • Great Insulation, Perfect Size
Style: 32 Oz Color: Black
The Hydro Flask 32oz water bottle has quickly become my go-to for staying hydrated throughout the day. It hits the sweet spot in size — large enough to keep me hydrated for hours without being too bulky to carry around. Whether I’m at the gym, at work, or on a hike, it’s the perfect companion. The insulation is seriously impressive. My water stays ice-cold for literally the entire day — sometimes even into the next. I’ve also tested it with hot beverages during the winter, and it performs just as well. The double-wall vacuum insulation does exactly what it promises. Design-wise, it’s sleek and simple but still feels durable and high-quality. I opted for a matte finish and it not only looks great but also gives a nice grip. The wide mouth makes it easy to fill, clean, and add ice cubes, and the lid seals tight with zero leaks. I also love that it fits in most cup holders and backpack side pockets, despite the larger size. If you’re looking for a reliable, well-designed water bottle that keeps your drinks cold (or hot) for hours, the Hydro Flask 32oz is absolutely worth the investment. It keeps me drinking more water, and honestly, I kind of look forward to carrying it around. ... show more

    • ~ Hydroflask Fan Since 2017 ~
Style: 32 Oz Color: Dew
Review Image by Sharon Sharon
Let me preface this by saying I've been a hardcore hydroflask fan for a while now. I was in need of a new water bottle and saw that this was on sale, so it was a perfect purchase! This hydroflask has held up nicely, and I love how I can shove it in my backpack and go, especially without it leaking. Super easy to clean with a bottle brush too! This has helped me drink more water, especially because I enjoy it ice cold, and this thing keeps it cold for a long time! I also want to add that this size is PERFECT. Not too big, but not too small either. Hopefully this review helped you in your decision and thanks for taking the time to read! :) ... show more

    • Nonstop Usage
Style: 40 Oz Color: Lupine
I don't know why, but the lavender/light purple version of this bottle chipped and dented far more easily than any of my other hydro flask. I also have this in a baby puke green and turquoise. They have held up wonderfully through heavy use and being taken everywhere. They get 5 stars. The purple one is a fluke, sadly. The color is gorgeous. I am still giving this review 5 stars because these are all I've used for almost 5 years. However, my heart breaks for the purple bottle that couldn't. ... show more

    • So easy to carry and no wrinkles around my mouth from a straw
Style: 20 Oz Color: Fir
This is my third Hydro Flask! I love these drink cups. I do have to buy the rubber bottom for them since they do dent if you drop them, other than that they hold up very well. The mouth has a wide top so it is easy to fill with ice. I enjoy that is does not have a straw to drink from. Not a fan of the straws since they are harder to clean and they cause wrinkles around your mouth. My drinks stay cold, I even have ice in my cup by the next morning if I have by my bed. I have never had one leak so that is not a problem. Many colors offered also. ... show more

    • DON'T TELL ME WHAT TO DO
Style: 32 Oz Color: White
I'm a heathen and I use this to keep my soda ICY cold for daaaaays. I think it says not to use it for carbonated beverages, but what can I say, I'm a rebel. This bad boy has reduced my ice makers workload by at least 50%. One fill up of ice is good for 6+ cans of cold soda. Get it to drink water, or be a cool kid and get it to fuel your unhealthy addiction. ... show more

    • Best Bottle Ever
Style: 40 Oz Color: Black
Love this brand waterbottle. Works well with different tops (based on your preference), keep water cold all day, holds a lot of water, and is great for kids to stay hydrated during the day. I have bought about 3 of these in different sizes because of how reliable my bottle has been and they all continue to be in great condition after over a year. ... show more

    • Ice melts overnight but water does stay cold.
Style: 20 Oz Color: White
For what it is, it works. Originally, I accidentally bought a couple of lids for this brand of water bottle thinking I was buying for another brand, due to the way the searches work here on Amazon, and held on to the lids until it was too late to return them. Then I eventually bought this bottle to match the lids. This bottle is a little smaller than the one I had, but that's just the size I chose, mainly because it was the cheapest. So, being smaller, obviously it doesn't hold as much water, but it does hold water and the lids I bought fit nicely. The main thing I'm not quite so fond of on this bottle is the insulation. With my original water bottle, I can put in ice cubes and water and the next day I'll still have plenty of ice in the bottle. Not so much with this one. The water WILL be cold, but the ice will have melted, so that tells me it's not quite as well-insulated as the other one, but maybe that's due to the smaller size. Other than that, it works nicely and has managed to fall and hit the ground a time or time with minimal damage. Overall, it's a good water bottle. ... show more

    • Rugged for travel
Style: 20 Oz Color: Goji
I bought this so I could use it while traveling for a few months. It’s been over a year and it still gets daily use. Perfect for the airport (empty) or while on trains and bus’s. Also for just daily use around town. I dropped it on a trail so it has a dent in it but still works well. Rugged.
