    • New Water Bottle
Color: Black Size: 64 Ounces Style: 64 Oz
Bought it for my Grand Daughter to replace the one she had inherited from her brother when he was in High School. The old one was past retirement age! New one arrived on time as promised. I didn't realize it didn't come with a straw lid just a plain lid. What self respecting young lady wants to tip a half gallon water bottle up just to get a drink? Not very ladylike! So we ordered a replacement lid with extra straws and she can now sip away like a proper young lady should. All's good! She now stays properly hydrated! And promises to put fewer dents in it than her brother managed with his. Hey its a water bottle! It arrived on time, keeps drinks cold all day, was a bit expensive, the young lady is happy, Grandpa got a hug! Life is good! Would I buy it again? Probably not...out of Grand Daughters! Yes I recommend this product! ... show more

    • ~ Hydroflask Fan Since 2017 ~
Color: Dew Size: 32 Ounces Style: 32 Oz
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

    • Worth every cent
Color: Black Size: 64 Ounces Style: 64 Oz
I’ve used it for around a year or two now and it’s definitely one of my most used and helpful item! It’s worth it and it keeps my water super cold even when placed inside the car for hours in scorching heat. It’s durable and can take a heavy beating.

    • Keeps your drink cold
Color: Moonshadow Size: 20 Ounces Style: 20 Oz
Love the color and perfect size for my ice water. Keeps my ice and water for hours. Love the wide mouth for filling in the ice and water. Great value for the price, especially when they have a sale. Perfect for daily use and easy to wash.

    • So easy to carry and no wrinkles around my mouth from a straw
Color: Fir Size: 20 Oz Style: 20 Oz
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

    • Easy to clean but impossible to open
Color: Fir Size: 1 Ounces Style: 32 Oz
This is my first hydroflask and I'm loving it. Easy to clean, keeps my drinks cold for a long time. But there are two reasons it isn't getting 5 stars. First, it leaks if I don't make a point to use a lot of force to seal it completely. And that right there leads me to the second issue - it is so hard to get open. Maybe I'm just weak, but it has to be screwed shut hard to not leak but then I can't open it again. ... show more
