I understand the cult following now...

I have seen the love people have for the Hydro Flask, but now I understand it. I got my 40 oz. blue flask yesterday, and is becoming on of my favorite pieces of gear. I am able to make tea in the morning when I am getting ready for work, and have hot tea all day!

...so good that I picked up another one!

Wish I would have never returned

LOVE LOVE LOVE this bottle.
Originally got the purple, loved the color.. thought the bottle was too big. I did return it. HOWEVER after ordering the 21oz bottle I changed my mind immediately and ordered another 40oz.

Love that I can get ice directly from the fridge straight to bottle. Worth every penny!

Took this with me on a very cold day with hot chocolate in it, was gone most of the day, and when I got back to the car it was still Hot.I would recommend this very highly.

love it!

I love this water bottle, it is by far the best one I have ever owned. It holds a lot of water and it keeps my drink cold for a very long time.

Awesome

This was my first Hydro Flask and it is awesome. I go snowboarding all the time and it keeps my drinks warm the whole time. I haven't used it to keep things cold yet but im sure it will work good if it keeps it as cold as it does warm.

Cold as ice

  • Familiarity: I've put it through the wringer

I live in a desert.
I'm active outside.
I LOVE a dose of cold water hydration after a long stupidly-hot summer bike ride.
I leave this full of cold water in my car.
It gets hot enough to fry eggs on the hood.
I return after HOURS on my bike and the water is still VERY COLD.
Awesomely refreshing.
It's amazing.
I wold love to see a 24 and/or 32oz wide mouth version.
I wold collect them all.
You should, too.

I purchased this because of reviews I was reading on a Disney site. I LOVE these flasks! My coffee stays hot for hours. I have not had a chance to use them for anything cold yet. I did however ask for more of these on my Christmas List!!
