    • Terrible!

Terrible! Had this for a couple months and the inside is all rusted! Past our return date so it’s a waste of money. We Do not recommend!

    • I love these water bottles
Style: 40 Oz Color: White
I absolutely love my Hydroflasks, and now have about 7 in different colors. I use mine everyday and ice remains in the bottle overnight and throughout the day. I'd actually probably have to leave it alone for days for all of the ice to melt and the water to get warm. I also like that it is insulated in the way that it doesn't sweat on the outside. I have the large, 40 oz bottles, which can be a bit large and unwieldy, but I like the large size for a whole day of work. They are super easy to clean, but since I only put water in it, I only wash the mouthpiece regularly. There is no weird taste transferred by the bottle. Overall, really, really love these and would recommend. I would say to make sure that you buy the Hydroflask from an actual, reputable site/dealer. I bought a few on eBay years ago and I don't feel like they work as well as my others, so they may have been fake. The ones that I have purchased through Amazon have been fine. ... show more

    • Fake, I don’t recommend
Style: 40 Oz Color: Black
Usually hydroflasks are better than this, I’ve owned many, this one is by far the worst, almost seems like a cheap fake replica, first one they sent me had dents in it, I returned it and got another, and it dents so easily, you can’t even place it down too hard, or bump it into your knee without denting it, the coating isn’t resistant to scratching at all, small scapes shred the paint/coating off, doesn’t retain cold/heat well either, I think this is a knockoff, very disappointing product. ... show more

    • New hydro flask came dented.

I got my boyfriend a hydro flask for Valentine's day to replace one that I had previously dented. He uses his hydro flask everyday and I felt so bad I literally cried when it happened. When we opened this one today he was so happy. After we took it out of the bag we then realized that the new hydro flask was dented on the bottom. The whole reason I bought him a new one was so it wouldn't be dented. This one was dented before I even got it :( ... show more

    • FAKE
Style: 32 Oz Color: Black
This is not an authentic Hydro Flask and they charge the same amount as an authentic. It was too late to return once I compared to my real Hydro Flask and realized this is a knock off.

    • Go back to old model

Prefer the older model that can hold the paracord handle. This new one doesn't have the lip needed to use it :-(

    • Worth it!
Style: 32 Oz Color: Alpine
Review Image by Samantha
I already own a 24oz Hydroflask that I take around with me, but wanted a bigger one to use at home and this was perfect. I debated between the 32oz and the 40oz, but ultimately chose the 32oz and I’m glad I did since I have fairly small hands. This gets pretty heavy when filled up with ice and water, but does it’s job of keeping your ice and water cold and frozen for 48 hours. Of note, I find if you don’t screw on the lid all the way, it loses pressure and doesn’t hold the temperature. Just make sure you screw on the lid the entire way and you’ll be set. The standard lid it comes with is leak proof as well, though I purchased the straw lid separately and won’t be using the standard lid much at all. Since this bottle is bigger, it also makes it so much easier to clean than my 24oz one. Overall after owning two Hydroflasks, a great water bottle that’s worth the money if you’re a cold water drinker! P. S. I ordered the new 2021 summer color Alpine for those of you wondering. Also want to note that I think this is the newer version that comes with the “new” logo according to their website. I got lucky with both my Hydroflasks because they were both wrapped in bubble wrap and didn’t come dented like some reviewer’s bottles. ... show more

    • Durable, super cute, and holds a lot of liquid.
Style: 40 Oz Color: White
Review Image by Na'kima
I love this Hydroflask. It's a little heavy, but that proves how solid it is. It keeps cold water cool all day, I put temperature Fiji water in it every night for my daughter to use the next morning for distance learning, and it's helping with her water intake. She's 95 lbs so she needs to drink 45 oz a day, with this bottle, she's only 5 oz off, but it's better than how much she was drinking before. I bought the boot, cap with a straw, and a bottle cleaning brush set separately, you need the boot because if you drop the bottle, or knock it too hard without one, it can dent. The caps with straws are available on Amazon also, and come with 2, plus 2 brushes to clean them, the boot comes with one, but is on this site as well. I bought one for myself also, it's a good way to drink half your body weight in water. I haven't tried hot liquids, and I probably won't, just water. It was a pretty penny, but it's quality, and I will pay for quality. ... show more
