Customer Reviews Hydro Flask 21 oz Standard Mouth with Standard Flex Cap

The Hydro Flask 21oz flask has been great for my early morning drives. I fill it full of hot coffee and it's still nice and hot 45 min later when I make it to the office. The mouth size is perfect and doesn't allow for easy over consumption. The fit and finish is great. It's very durable, but we hand wash any way.

I got this, because I needed a sturdy, quality bottle to hold my drink while I am working or doing any tasks where cold or hot refills are handy. I have to say, this exceeds my expectations by far! I have used this in hot weather. when traveling to warm climates, for 6-8 hours and still had ice in my drink! When returning home to my colder season, I filled this with steaming hot tea, and sent it to work with my husband who works in the colder climates, and he said that he still had steam after over 6 hours! This water bottle is amazing! I also love it's bright blue color, which makes it very easy to spot amongst other cups at my job. This is easy to clean, and the hard yet lightweight aluminum construction makes it a tough cup which I like so it doesn't get scratched or dented easily. I can't say enough good things about this cup! My husband is getting one for himself, and wants to get one for each of our kids! I have recommended this to multiple of my coworkers and friends, and they are all going to get their own!

I have seen this popular brand for years but have never tried it. It has really been a great addition to our water bottle game. We have only used it for water but it keeps it nice and cold for a long time. It's not too big around so we gave to our 6 year old daughter to carry to school. Overall a great product.

I received a Hydro Flask 21 oz Standard Mouth- Pacific to test and review. Very nice metal bottle. It keeps cold beverages nice and cold. This great quality bottle is easy to take wherever I go and doesn't leak.

I love this hydro flask! It works super well. First of all, the color is beautiful. I love the size since it fits in all the drink holders I put it in. And I was so impressed with how well it keeps my water cold. It lasted all day. It says it is dishwasher safe though I've only hand washed it. Overall, a perfect flask for on the go.

Love this flask! Keeps drinks cool for hours! I like that you can switch out different lips and gives you options. Would definitely recommend to friends! Will definitely order a larger size also! Thank you!

Love this sleep water bottle and the handle. Most important it fits in my car cup holders! The color is so pretty and I love that the handle has a little flex. I dropped it the other day and it didn't dent or scratch. It is also a great size to put in a backpack for school. Water has been kept nice and cool! Love it!

My son loves it.. Uses it for Everything.. Great Product

I used this Hydro Flask for a cold drink and I couldn't believe how cold it kept my drink. I have used others that promise the same thing that really doesn't. Hydro Flask works so much better. Would buy again.

Love this bottle for my daily water. Keeps water cold for hours and fits perfectly in my cup holder. Love the color also and all the colors that hydro flask offers. If you are looking for a new daily water bottle I'd definitely recommend taking a look at these.

This HydroFlask is the perfect size for my son's backpack. He's been taking it to school everyday since we bought it, and it's worked really well for him. It fits in the side of his backpack where a plastic water bottle usually fit. I also like the color of this Hydro Flask. It is hard to miss it or look over it. It stands out.

Hydro Flask is top notch quality and I have yet to have any issues with their bottles or other containers. This bottle is no exception as it keeps my drinks hot or cold for long periods of time and I have not had any leaking issues. These are the prime areas I look for with my bottles so I am very happy.

This is a great size to take to work, walks, etc... I put iced coffee in it for work and it was still cold when I left. It has a great handle on the top which makes it very easy to carry around. The quality is wonderful as well

I just got this Hydro Flask 21 oz Standard Mouth water bottle and it is easy to clean out, doesnt have any weird taste to it and keeps my water cold or warm depending on what temperature I want it to be

Hydro Flas has an excellent product. Very well made and very nice looking. The fit and finish are high quality. The lid fits well and seals tight. No need to worry about leaks. This is an excellent purchase for anyone looking for a high quality flask.

I am absolutely in love with this Hydro Flask, Standard Mouth. This product is well made from a high quality stainless steel. I really impressed with this bottle, it can keep the cold water up to 24 hours and keep the hot water up to 12 hours, so it's a perfect companion to bring for camping or hiking. It's also BPA&Toxin free, so it's safe for my whole family member. I really like the colour of this bottle, very cool and nice. It also included with a standard mouth cap, super easy to open the bottle, and it works great to keep the water stay inside the bottle without leaking out. This bottle is dishwasher safe, so I don't need to work hard to hand wash this bottle. I am highly recommend this product.

Love it!! It was a gift and he really loves it and uses it every day

I think overall it is a great water bottle! I defiantly recommend it. I think the main reason I fell in love with this water bottle is because it is such a great size. Not too small, not too big. It's also really durable (keeps my water really cool, for a long time) I think it is worth the price. The only thing is a wish it came in more colors, I got the color eggplant but from another store I wish hydro flask sold that color on there website as well. Other then that, it's an excellent water bottle.

Great bottle. Perfect size to fit in a backpack for school. Love the color!

Been using Hydro Flask for 5 years, it is still going strong. I'm buying one for my partner so we can have our own ;D

Best water bottle I've had :) Fits in every cup holder you can think of while not being too small in terms of how much it can hold. Ideal

Bought for my teenage daughter to take to school every day - she likes it, says it keeps her drinks cold.

This water bottle is sleekly designed and does the job of keeping water cold, which is especially appreciated on these hot summer days!

Had one given tome brand new. Bought another one (identical model, different color) for my son. Super impressed with quality and function. Now that I've begun to use mine regularly, now that I bought a sport cap to go along with it, I've come to the conclusion that I drink water fast and probably need something bigger than 21oz. Will happily buy another [larger] model in the near future...that way I can go on longer outings before needing a refill. Hydro Flask keeps cold water cold all day long which is REALLY nice!

I love the sport top for drinking while playing golf and the quality is second to known.
