Hydro FlaskWide Flex Cap Black 64 Oz

The water bottle works great. It keeps water chilled rather well.If you're in it to save some plastic, great! It'll last you a long time. If this is your 5th one, I think it defeats the purpose of being "green." But that's a different conversation.How cold does it stay? Long enough. If you want it to stay cold 12-24 hours, that also defeats the purpose. Drink your water. Why do you need your water to be cold tomorrow? Drink your water today.What I love about this compared to other bottles I've used before or seen:* Wide Mouth - easy to add ice. Easy to drink out of. Easy to clean.* No Straw - no concern about getting Smoker's Lines.* Size - some other bottles of the same external size are about 32 oz vs. 40 oz.* Handle - Fun to swing.* Doesn't Spill.

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.

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! :)

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.

Love the bottle. I have waited for awhile for it to be delivered as it was short on order. Like the size and easy for carrying. Keeps the water cool through the day

These flasks are really great. They’re incredibly sturdy, made out of steel; and the drink inside stays cold all day. I use it constantly; I take it with me on drives and on walks; it’s always sitting on my counter with something in it to drink.

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.

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.
