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

I'm always rushed in the morning and don't have enough time to make my coffee. When I received the Hydro Fask for free from the Tryitsampling Community I put it to the test. I made my Coffee at 10 pm the night before and put it in the Hydro Flask. I wanted to see if it would keep it warm til the morning. It sure did! I opened the Hydro Flask at 8 am and the coffee was still warm! My only concern is that it didn't have a spout and you have to be careful not to spill your drink.

I used the Hydro Flask for both my water and my coffee. I wanted to see how well it would do for both. I filled up my flask before work (7am) and only drank about half. When I got off work at 6 my coffee was still hot and ready to drink. The next time I used the flask I added ice water. I drink a lot so I brought an extra water bottle with me just so I could test how long the water in the flask would stay cold. I added ice water at 7am and checked it at 2. The ice had melted but the water was still very cold and refreshing to drink. I appreciate also, the handle on the lid. This feature makes it easy to carry no matter where you go. The cap twists on easily and if toppled over, does not leak. My thoughts on the Hydro Flask are that is stands up to both hot and cold, is easy to carry and all out a great product. I would definitely recommend!

Tried the Hydro Flask 21 oz standard mouth in white and loved it. Liked that the bottle doesn't sweat. I put ice in it at night and my water was still cold 8 hours later! Easy to clean and great size.

My husband loves this water bottle! It keeps water cold all day. My biggest concern was water having a metallic taste and for the first use it does a little, but once the bottle is washed more than once the metallic taste fades. The cap is very secure and the bottle does not leak if tipped over with the he cap tightly on. I would definitely recommend this product!

I received this Hydro flask from try it sampling and this item is great! It keeps my ice an water cool all day while I am at work. Also it is easy to use and fits in my work bag without any problems. It is just the right size.

I received my HydroFlask a few days, and I took it on vacation to the beach with me... In the morning I used it for coffee as I did shopping. I was amazed that my coffee stayed warm!! I took it to the beach in the afternoon with a cold drink, I was absolutely surprised that my drink stayed cold as the day got hotter!! It was like having a mini fridge !! This is the best of both worlds! !!

I live in Florida and I bought these in several colors. When I received them, they seemed to work great but I wanted to put them to the test. So on the day the temperature was going to be 101 degrees, I took cold water and filled the bottle. I did not add any ice when I filled it. I put it in the car at about 9:00 am and left it in the car all day, some hours having the car parked in a non-air conditioned garage with all the windows closed. At 5:00 pm, we left to run an errand in the car. I took a sip from the bottle, and even though the bottle was extremely hot to the touch, the water inside of the bottle was as cold as it went into the bottle. I actually did a Facebook demonstration and measured the results with a thermometer. If this doesn't convince you to try this, I don't know what will. I highly recommend it, and in FL it's a Godsend to be able to use this in the car. The bottle also cools off quick when you turn on the air conditioning.

I've been using this water bottle for over a month now. It's my number 1 favorite cup ever! It keeps my drinks so cold and the ice never melts. I take it to work with me and because it holds a good amount of drink it lasts all day. I saved so much money on bottled drinks with this cup.

This is a very nice bottle for carrying around. It keeps cold drinks cold and hot drinks hot for a couple of hours. Its easy to keep with you and its very handy. It fits perfectly in my car cup holder. I would love to have a lid with a straw. This is great when on the go!

I recently received this bottle/flask and have been taking it with me every time I go to the gym. After a workout, having cool, not completely cold, water is so refreshing and gets me well re-hydrated. Usually I have to fill my previous bottle with cold water and by the time I finish my workout, it is just cool enough. But with this flask, I fill it with cool water and stays cool!

This bottle was exactly what I needed. It's great for anytime whether home or traveling. It keeps my drinks super cold for a very long time. The pretty Cobalt blue is a plus too! This is a perfect bottle for anyone of any age

The first time I used this, I filled it with coffee and rushed off to work...leaving it on the counter. I got hit with a double that day and by the time I got home, I was too tired to bother with it. When I went to dump it out...over 24 hours later...the coffee was STILL warm!

The Hydro Flask 21 has been fabulous the past few weeks. Beverage remained cool for a long period of time. I was worried that there might be a metallic flavor but as glad to find that there was not. Flask color- yellow- was bright and fun!

This is an excellent hydro flask. It is made of good, sturdy material. It kept my drinks cold while in the hot sun. I also liked the colors offered to buy the flask in. I would recommend this flask to anyone who wants to enjoy the outdoors and stay hydrated.

I am a huge coffee drinker and need my coffee to stay warm all day. I am a mom and I work so having a hot cup of coffee and sometimes impossible. I was able to try this product out, and I have to say it does exactly what it says it does. I'm able to fill my cup up in the beginning of the day and by the afternoon it is still warm. I have only used it for coffee and have loved having it by my side all day. If you are on the go the majority of the day this is what you need.

I received my Hydro Flask a few weeks ago. I very surprised with how well made it was. I've taken it to work several times. It always keeps my ice tea very cold even after several hours. It is very well made and sturdy. I love it!

I actually have a million water bottles and this is my go to because I like my water extra cold, especially when I'm working out, and this keeps the water very cold for a long period of time. I really like the look too!

I received this bottle for free to review. I absolutely love it. It keeps my water super cold and refreshing! I highly recommend this for workouts, hiking, day trips, etc. . My only issue is that my daughter loves it so much that it will probably disappear!! Definitely recommended

Love my new cup. I have a collection of cups. This is one of my favorites. Love the color and keeps my drinks cooler longer. I would recommend this product to anyone. The product is a good size. My favorite cup by far!

I bought this for my sister for Christmas last year, and she loves it so much, and now I have my very own. This water bottle is ridiculously gorgeous/stylish - so much so that I think I'm drinking more water now just because I want to carry it with me everywhere I go. It's a great size and weight and seems very durable.

Good size. Bright vibrant color. At first it had a slight metallic taste/smell but after several washings it resolves. I wish it was dishwasher safe but otherwise it's great. Keeps cold drinks cold and hot drinks hot.

This bottle is great! I cannot believe how long it keeps my beverages cold. I left it in my hot car for 8 hours and came back to ice water. It is also very tough. My kids have dropped it on concrete and it did not dent and had no leaks. Great product!!

I got this too try and now I am in love and obsession. I take it everywhere and fortunately it works for either cold or hot drinks. I love the turquoise color and the thick top strap. People have asked where I got it... Fun to be there trend setter!

I recently started using this and could not have been happier. I have to drive a lot and was always worried about carrying water in plastic bottles and leave them in the car. Not only the material of this bottle is awesome, it retains the water temperature quite well. The bottle looks very stylish and I have been asked by people in my gym on where I got it from. It's wonderful to finally have a water bottle that keeps the water cool for hours.

Love using this bottle to get my daily intake of water. My water stays cold all day long while I'm at work. It's easy to use and cleans well. Love the pretty color of the bottle as well. Fits in the cup holder of my car well also.
