  • I received a dirty, used product!
Size: 18 oz Color: Cobalt
I ordered a hydroflask from amazon a few weeks ago, and I loved it. Decided to order one for my mom as a gift. Today I received it, and it hard old coffee stuck inside and outside! So gross! I can’t believe amazon let this happen. Make sure you check the product before you give it to someone as a gift! ... show more

  • The Lost Secret of Atlantis!
Size: 18 oz Color: Fog
Languishing from a lack of water? Need to drink at at least 100 oz a day? Want to give Aquaman himself a run for his money and bring home the lost flask of Atlantis? Look no further! You've just discovered the most powerful hydration weapon in all of the Underwater! I have literally gone from struggling to drink 50 oz. of water a day to easily drinking 100 oz. This flask is my new best friend. All I do is fill it with ice in the morning and refill it throughout the day at a hydration station at work or from the water dispenser in my home fridge, and I'm set to receive all the icy goodness that refreshingly cold water can bring. And, yes, I did say from home because I don't even use drinking glasses at home anymore. It's literally a pain to get up and prepare a glass of tea or lemonade. I'm seriously asking myself "How much do I really want this?" because my hydro flask is right there already filled with cold deliciousness. If you're looking for a way to rediscover water in a way you never thought possible and make your doctor proud, this is great start. And, don't be discouraged by the price. It's worth every penny. I've yet to use it for hot liquids or soups, but based on the fact that my ice keeps often for longer than 24 hours, I highly doubt it would lack to do what it claims on the opposite end of the spectrum. I'm seriously thinking of gifting these for Christmas, and I'm not a water bottle or "health nutty" type of person. They just make sense, and they're just that good. ... show more

  • Coolest Water Bottle
Size: 18 oz Color: Cobalt
Bought this for my son in elementary school. The water bottle itself seems really sturdy, which is a huge plus for us! It seems to keep the water much colder than a plastic type water bottle. I don't tighten the cap too tight so my kiddo can still twist it off but we haven't had any issues with leaks. I plan to buy a few more - spread out as they are a little on the pricey side!! ... show more

  • Hydro flask customer service 5 stars
Size: 24 oz Color: Fog
Purchased for my daughter during the pandemic because they are not allowed to use water fountains anymore. After being dropped by her several times it began leaking. I went to the hydro flask website to see if there was warranty and there is! Called and reported the problem and with in a few days a brand new HF was shipped to me! Couldn’t be happier with customer service and support from this company. Yes these cost a little more but when they stand behind their products then it is worth it not to get stuck with a disposable piece of junk that you will have to pay to replace several times. ... show more

  • Don’t buy!!
Size: 24 oz Color: Fog
Do not purchase this, honestly I’m not even sure this is a real hydro flask. I started to really stink after one day like super moldy smelling, I washed it again then two days later same Thing. I have a separate hydro flask I got from the actually company and NEVER had this problem

  • Great Temperature Regulation and Aesthetically Pleasing
Size: 24 oz Color: Fog
I never understood the hype about Hydro Flask until now. The beautiful aesthetic exterior is so appealing and smooth. There’s a variety of colors but I went with the Fog and love it. It’s almost white but with a hint of purple. The best part about this product is how long you can leave water or any drink in here for. I filled it with cold water at about 11 pm when I was going to bed and when I woke up around 9 am it was still ice cold. Now I drink water more than ever and even found ways to add flavor such as throwing a lime or lemon in there. I can’t wait to buy my next Hydro Flask! ... show more

  • Durable as hell.
Size: 24 oz Color: Fog
This bottle is a combination of all the good qualities with none of the bad. I can actually fit ice in the hole. It’s not too big where it can’t fit in a car beverage holder. It actually keeps water cold if there is enough ice to start with. Bonus, it accidentally rolled around the floor of my car and to my surprise…not a scratch. ... show more

  • Easily Damanged
Size: 24 oz Color: Fog
This hydro flask looks like it has been through it. I have dropped it twice at work just off a desk and it has dented half the bottom so now my bottle sits crooked. It even had a bumper on the bottom that I thought would protected but didn’t. It also landed wrong and dented the top of it. Very disappointed at the quality of it for it to dent so easily at the price point. ... show more
