Bought this for my daughter and she absolutely loves it. Loves taking it to school and her dance lessons. It makes her so happy

I bought it a month ago and have used It extensively with multiple different liquids. Has held up great and it keeps my drinks hot and/or cold for a long time. It also feels and even SOUNDS amazingly satisfying.

I brought my daughter a hydro flask for Christmas. It's the cool thing for middle schooler to have a hydro flask. I got hers in white and added a pink top and pink boot with some waterproof decals and she takes it with her every day

Bought this for my granddaughter, and she loves it! It goes with her everywhere.

Purchased for my housekeeper's daughter who very much wanted this flask; and, daughter was thrilled with it@

Kids Love them, kinda Pricey but better than having them use plastic bottles

This is my 3rd hydroflask, I have one for home and the office, 21oz and 40 oz. . I have been using these products for the last 3 years and it is wonderful. Live in Florida and work on boats and my hydroflask always keeps the water ice cold. The bottles have taken many beatings and hold up well. Easy to clean and well worth the investment.

I really love how my drink stays cool for so many hours.!

From the packaging to the finish Hydroflask keeps making great quality products!

I have 1 bottle in this size and it is great if I am going out for a couple hours. Keeps my water very cold and isn't too large to just carry around.

i think this water bottle i amazing and i totally recommend it for you but here is a quick note the top is the most sensitive part

I got this for my my 12th birthday and i loved it i got it in ice blue i recamend this and its a fordable

I've had this bottle for a couple years now I use it on my bike winter and summer. Prior to this I tried plastic (awful taste & warm water after an hour or so) and then I tried stainless uninsulated (better, but still didn't hold the cold). I finally bit the bullet and sprung for this nifty, red bottle. I love it! It fits my bottle cage perfectly and looks great against the silver frame on my bike. It keeps the water cold even in 90 weather, sometimes even into the next day if I forget to refill. At first I was disappointed that the powder coat became scuffed and in some spots even worn away. But I came to realize that no finish could hold up to the abrasion from a bike bottle cage, so this has become my dedicated bike bottle. It looks like it's been through the wars, but I wouldn't give it up! Since then I bought another black one that I use in the car and for walking around. And just recently acquired a third just because. I would not hesitate to recommend these to anyone. I also picked up the 10 oz rocks tumbler with an insulated lid. Keeps my coffee hot for a crazy long time!

It just works. Every plastic bottle I don't have to buy now is just one tiny way of helping to save the planet. Water stays cold all day. Or hot if you like. Built to last, a great way to stay hydrated all day.

buy buy buy buy buy it because it's such a great bottle

I bought this a few weeks ago and can honestly say I love it so much. Water stays chilled all day long. The exterior durability is fantastic and has survived serval drops.

I bought this a month and I'm in love with the color I got. I keeps my water cold all day

This Hydro Flask I a great Price compared to the other I have seen.
