Good deal & works great
The flask has worked fine to carry water when golfing. Stays cool for quite a while. The only problem has been that I filled it and tossed it in the passenger seat to drive to golf. I accidentally left the sport nozzle partially open and emptied about 10oz. Into the seat on the way to the course. Otherwise it works great, just like my other HydroFlask.

Such a good bottle !
I bought this early may and I’ve been using it non stop. It is really good for sports and very easy to use when pulling up the cap to drink!

Love this style!
I bought this for my daughter and the sport top is perfect for her to carry around and keep her drink sealed and cool. She uses it daily and takes it everywhere, her drink stays cool even when left in the hot car while we run into a store. Would definitely purchase again!

Love the cap!
I used to have a straw cap for my other hydros, but the sports cap is so much easier to use!

Love it...as always!
I bought this for my post-pandemic return to the office, since I planned to start with something new and clean. Unfortunately, we are not allowed to bring in personal water bottles into the office ...yet. I will keep it safe until then!

Love this style !!
I have a number of other Hydroflasks but I was interested in this style so that I can have cold water after finishing a run (that I had to drive to so I wanted to be able to leave this in the car). It is great and keeps the water cold for hours — love it !!

Great!!
I bought this a couple of months ago and it has been amazing!!! The water stays cold for hours even out in the southern summer heat!! I didn’t think I’d like the sport cap, but I grew to love it, I can leave it open and get a swig whenever I need it rather than having to open it every single time I want a sip.

Love it!
I haven't had my Hydro Flask for long but I already think it's great. It's just the right size to take on short hikes, or to work,or just sitting around the house. The lemon color is so cheery too! The handle makes it easy to take wherever I go.

Customer services made me a repeat buyer
We received a damaged item and a customer service rep (Cheryl) was proactive and thoughtful in correcting the issue. Based on service alone, I will happily purchase more products from hydroflask in the future.

Questions
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

Can anyone recommend a bike cage for this bottle? I tried a plastic one to hold the bottle but the bottle was too heavy for the plastic and broke. I now have a metal cage but the metal on metal makes a lot of noise while riding my bike.
We regret to inform you that our products are not specifically designed to be carried in bike cages and they have not been tested for such use. We would be concerned about the possibility of the cage causing scratches, chips, and dents to your flask from improper fit and jostling. Therefore, we do not recommend carrying Hydro Flask products in bike cages.
