Perfect size!
Was looking for something that would fit in my husband’s new car water bottle holder. A thirty dollar water bottle and a luxury car... match made in heaven. Darn you, German engineering! But thank you, Hydro Flask!
(Also, I already owned one and have loved it for 4 years now - perfect size for a normal day of going around town!)

Beautiful bottle
I love this bottle. It’s reasonably lightweight, keeps my water cold for hours upon hours (even when the bottle is sitting in the sun), and the Fog color is even prettier in person.

FINALLY A WATER BOTTLE THAT WORKS!
Bought this for daily walks and every day use at home! Fits in car cup holder! I can drink easily while driving without taking my eyes off the road. Keeps my water cold without ice cubes! I have several of them! I don’t use plastic water bottles any longer! I’m done spending hundreds of dollars on water bottles that don’t work!

I like it , what can I say
Bought these (2) to replace "plastic" bottles in which the water always tasted like plastic. Stainless interior of the Hydro Flask give a much clean taste.

Questions
Do they float? I'm looking for something with a closed lid to use on my kayak and with the possibility of flipping the kayak I would like to make sure I will be able to locate the flask if that were ever to happen.
Hello, I do apologize about the longer response time!
No, with the flask being filled they would not float. They may float if they happened to be empty at the time but I cant guarantee that.

Will this size fit in a standard cupholder?
Hello, Thanks for reaching out! I do apologize for the long response time!
Yes, the standard mouth bottles usually do tend to fit inside a standard cupholder!

I bought my Hydro Flask at Dick’s Sporting Goods will I still be offered the lifetime warranty?
Yes, it is covered under our lifetime warranty for manufacturing defects.
Date published: 2020-11-05
Are any of the water bottles dishwasher safe?
According to the Dick's Sporting Goods packaging my 24 oz small mouth i just received is dishwasher safe? Amazon is also reporting they're dishwasher safe. But I see no marking on the bottom that says it's dishwasher safe. Please explain

I am getting a metallic taste in my water from the 21 oz flask. I’m surprised as it has 18/10 stainless steel. Is there anything that would get rid of this?
We understand how frustrating treating odors can be, but we have a quick trick to battle the issue: Mix 2-3 Tablespoons baking soda with a small amount of warm water to form a paste. The paste is a nonabrasive scrub and deodorizer. Rinse the flask with warm water. Then wash with regular dish detergent.

Can I use the lid with the straw for coffee in the standard mouth 24 oz bottle
Our Wide Mouth Straw Lid is compatible with all of our Wide Mouth Bottles. Unfortunately, the 24 oz bottle is a Standard Mouth and is not compatible. We have our Standard Flex Cap and Standard Sports Cap that will fit the 24 oz bottle.
Date published: 2020-01-27
Where is this bottle manufactured?
Manufactured in China but shipping from Southaven, MS.

Is there a cap available for purchase that would allow me to use my standard mouth Hydro Flask 21oz with hot drinks? I purchased 2 hoping to use one for hot and the other for cold. However I have not been able to use hot drinks due to the cap. Frustrated
We currently have two caps for the standard mouth flasks. We have the sports cap and the flex cap.
