    • Small mouth
Excellent quality and insulation as always for Hydroflask. However, it's hard getting the ice into this with such a small opening at the top. Also, it knocks down more easily since it's tall and skinny. I had to buy another one that's bigger at the top and now use this one as my extra backup.

    • 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

    • 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

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
