5.0 out of 5 stars Favorite water bottle.
Reviewed in the United States on November 29, 2024
Easy to carry everywhere ( work, home, gym, on the go ). Love the color and how it keeps the water cold after hours of adding ice. I can’t drink water that is room temperature, even in the cold I have to add ice. Does not leak and I love the big opening. I’m not a fan of water bottles with straws or sip straws or other openings where barely any water comes out or you have to suck on it for the water to come out. I think this opening helps me drink a lot more water. And I like to refill it more than my 32oz, but it has been helping me a lot with my water intake. It is easy to wash. I also take it with me to the gym and fits in every cup holder that the machines have for your bottle. With my 32oz I have gotten some of them stuck in the cup holder or with 64oz I have to leave it right next to the machine. But with this one it is easy to take a quick sip or long sip. It is easy to open and close. I just bought another one in the other shade of purple because I am obsessed with it. Definitely a perfect replacement for your water bottles ( lost 2, and broke 1 ) and over other good brands this is so far my favorite. Highly recommend it, worth the price!

5.0 out of 5 stars Keeps Drinks Cool, Great for Hiking & Traveling
Reviewed in the United States on August 25, 2024
I recently bought this for a trip to the Dakotas and love it! Was perfect for traveling, hiking, and visiting national parks. It's a good size that fits in cup holders and backpacks, but not too small. I really like the cap, very secure and tight. No issues with water leaking from the top. The double wall kept my water really cold. My Yeti cup works slightly better for keeping ice from melting, but this is more cost effective and has the better lid for sealing in the drink. Great hydro flask!

5.0 out of 5 stars great water bottle but...
Reviewed in the United States on August 19, 2024
I got this size water bottle because it's not too big and not too small. I just used this in a Chevy suburban and the bottle fit just right in the cup holder. I got the lid without the straw and it has a nice carry handle. I will buy the lid with the straw for future use because it is not easy for me to drink from this bottle when the car is in motion. the car stopped and I wasn't paying attention and the water spilled on me. if I had a lid with a straw that would've never happened. the bottle is good as is for hiking because I can just stop and drink from my bottle. if you intend to use this in a vehicle I would get the lid with the straw. the bottle kept my drinks cold. didn't test it for hot drinks yet as I am writing this review in the summer. it was a little pricey for my usual budget but I find it is worth it because so far the bottle is very durable and it seems it will last a while. the bottle is also easy to clean. so far so good!

5.0 out of 5 stars Better than most bottles
Reviewed in the United States on November 20, 2024
As someone who’s always on the go, my Hydro Flask has become an essential part of my daily routine. The insulation is no joke—it keeps my water ice-cold during long training sessions and my coffee piping hot when I’m heading to early morning workouts. What really stands out to me is how durable it is; I’ve dropped it more times than I can count, and it barely has a scratch.

The wide mouth design makes it easy to fill with ice or clean after a long day, and the sleek design fits perfectly in my gym bag or car cup holder. I also love how it doesn’t sweat, no matter how cold the contents are, which is a huge plus when you’re carrying it around all day.

For athletes, travelers, or anyone who values convenience and performance, the Hydro Flask is worth every penny. It’s not just a water bottle—it’s an investment in staying hydrated and fueled no matter where life takes you

The flex cap makes it easy to carry and pour without spills. I love the durable design and how easy it is to clean. Plus, it comes in so many fun colors! It’s become my go-to water bottle for everything—highly recommend!

4.0 out of 5 stars Beautiful bottle which dents very easily.
Reviewed in the United States on October 31, 2024
We have other big-brand water bottles, but I wanted to try this one. I like its size and shape; it's beautiful and well-built. I even got a matching boot to prevent dents. However, on the third day, it fell on the marble counter and dented easily. This is surprising for a bottle advertised as durable steel. The care instructions are also confusing, stating it's dishwasher safe but also saying hand wash only. Given its fragility, I'll stick to hand washing. It does keep water very cold, though I haven't tested it with hot liquids yet.

5.0 out of 5 stars Is a Pricey Water Bottle Really Worth It? Hydro Flask Says 'Heck Yes!
Reviewed in the United States on November 7, 2024
In the endless ocean of water bottles, why splurge on a Hydro Flask? Because it’s actually worth it. If you’re finally ready to level up from that freebie bottle from the dentist, let me tell you—this is the ultimate hydration vessel.

After a few months with my Hydro Flask, two things stand out: durability and ice-cold water. I’ve dropped this bottle from heights that would leave lesser bottles in pieces, and it just shrugs it off, looking as cool as ever. And speaking of cool—this thing keeps water cold even after an hour of hot yoga, which is practically a superpower.

Plus, let’s face it, Hydro Flasks come with a certain “I’m hydrated and I know it” vibe. So, if you’re waffling over spending a little extra on a water bottle, just know I did, and I’m now sipping ice-cold water like a boss.

5.0 out of 5 stars The Best Water Bottle I've Ever Owned
Reviewed in the United States on July 9, 2024
I've been using the Hydro Flask Stainless Steel Standard Mouth Water Bottle with Flex Cap, and I am absolutely thrilled with it. The double-wall vacuum insulation keeps my drinks cold for hours, even in hot weather. The Flex Cap is incredibly convenient and makes it easy to carry around. The stainless steel construction is both durable and stylish, and I appreciate that it doesn't retain any flavors from previous drinks. Whether I'm at the gym, hiking, or just on the go, this water bottle is the perfect companion. Highly recommended for anyone looking for a reliable and high-quality water bottle!
