Hydro FlaskWide Flex Cap Black 64 Oz

Keels water coolNot as heavy as other competitors

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.

I absolutely love this water bottle. Drinking out of it is so nice and crisp feeling and the water stays very tap cold (or fridge cold if you prefer). I'm so happy to have a water bottle again and it's super nice to have an insulated metal one because now cold will stay cold and if I happen to have tea in it, that will stay hot :) I'd give this 10 stars if I could.

I love the Hydro flash brand. In fact, someone else loved it so much they stole mine at the gym. I ordered two more to see if I could go up a size for more liquid intake. And unfortunately, the larger one has too wide a bottom to fit in my car. The 20 ounce one was perfect.

I have been using Hydro flask for many years and have never been disappointed. Give my liquid cold and integrity of the bottle has stirred up over time. Highly recommend.

Stays hot enough, long enough. It is a good company.

This is very good. Holds water as well as ice. Easy to carry and very easy to use

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.
