STOP RIGHT HERE! YOU WONT BUY ANY OTHER!
I have tried many, many, many other water bottles..they leak, too big for most women to hold on to, and on and on. BUY HYDRO FLASK water bottle and you will never buy any other. I have two, so I can always have one in use. I walk every day and this goes with me!
Yes they fit in my car cup holder! Couldn’t be happier!

Keeps water cold
This water bottle cap is a better quality than the others, it keeps water cold but unfortunately my daughter already lost interest in it and likes the $10 water bottle from target better. The quality is good but overpriced in my opinion.

Love this!
My daughter bought me one and I loved it so much, I bought everyone in my family one. We live in a dry area of the country and I love having ice cold water to keep everyone hydrated. And we don't use bottled water any more so no more piles of plastic bottles. Healthy for us and the environment!

My Wife Lives It!
I bought the bottle and boot for my wife. She has always been jealous of me and my 21oz. HydroFlask. She has had other brands and has not been happy with them for one reason or another. She calls her new bright yellow HydroFlask, Perfect! Need I say more.

Perfect for sports and school
I bought this a few weeks ago right before school started and I’m so happy with it. My daughter gets so excited that her water stays cold all day at school! And the sport mouth is perfect for kids as well!

a step above
I bought 2 of these for my adult daughter and I. So happy I did, ice stays cold for more than 24 hours. Fits nicely in my car drink holder. The top is designed well and easy to grab with 1 finger and carry. I hesitated because it is a premium product which comes with a higher price but really the best thing for really ice cold water storage.

The perfect bottle
So happy with my purchase. Found my favorite color and it happened to be on sale. Keeps my drinks super cold and even when it’s all the way filled up it’s lightweight. Getting the sports cap was the cherry on top because i’m able to drink from it without taking the whole top off and i’m still able to carry it comfortably.

Ice, ice, baby
The ice can't melt in this thing! Makes a great gong noise when it bumps against things.

Questions
Are all Hydro Flasks dishwasher safe?
No, only the new 2.0 bottles are dishwasher safe. You can reach out to us at 888-584-9376 to determine if your bottle is dishwasher safe or not.

I would like to know if you guys still sell the mint colored 21oz standard mouth bottle. Also, do you guys bring back old colors? It was my favorite but I lost it and I can't see myself without that lovely color!
At this time we are not making the Mint color. Product colors are based on consumer feedback. I will forward your suggestion over to our product development team.

Can I order this bottle but with the flex-cap? I noticed that they don't offer the 21oz Standard Mouth w/ flex cap in the "frost" color.
The 21oz standard flask that comes with the flex cap is currently out of stock in the color Frost.
Please contact customer service at 888-584-9376 to discuss this further.

My bottle has a rattle has something broken inside?
The rattle you hear is a small metal disc that sits between the double wall of your flask that aids in the vacuum insulation process. If the disc becomes dislodged, you’ll hear a small gritty noise or rattle. This will not affect the insulation or structural integrity of your flask.

Is the sports cap easy to open? My mom has arthritis and is looking for a water bottle she use easily.
When the sports caps are brand new, they can be a little hard to open and close. I would recommend a wide mouth flask with a straw lid.
Date published: 2019-10-29
what lids can be used with this bottle besides the sports cap and the flex cap?
The Standard Mouth Sports Cap and the Standard Flex Cap are the only caps available for the standard mouth flasks at this time.
Date published: 2019-10-27
Are you able to put ice cubes in the standard mouth bottle or is it to narrow for ice cubes to fit through the top?
Normal sized ice cubes will fit in the standard flask.
Date published: 2019-10-27
So this bottle works w both the sports cap and the standard sized screw able lid?
Yes
