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

I received a wonderful new Hydro Flask 21 oz Standard Mouth (Cobalt color) for free recently to test out and was quite impressed. To start, it's a great size (not too big, not too small), nice color and finish (I really like the more textured finish, it doesn't show seem to show scratches and such, plus you can hold on to it better ...). Then, to the more important points; it's great at doing it's job ... keeping liquids at temperature! I live in Florida and we've had a ridiculously hot/humid summer (into fall) ... well, I've placed cold, ice water in the Hydro flask, left it in the 'hot' car all day ... on returning off and on all day I found the water (and ice) remained refreshingly cold ... it was wonderful!! I then tried it out with some hot cocoa and it stayed nice and hot for over 12 hours ... I think my only fault was that it is a bit heavy (especially when full); so might not work great for an outdoor activity of much length (to carry). So overall ... I really think this is a keeper!

The design is simple and sleek, easy to clean too. It kept my ice water cold on a 5 hour zoo outing. There was even unmelted ice cubes when the water ran out. No dripping condensation made it easy to store in my bag with fear or messing up the other items.

Excellent quality, perfect size and beautiful color, my water stays fresh forever... Reasons to love: - No disgusting metal taste - EVER - Hydro Flask is great for hot drinks, too! Fill it up with tea, cocoa, or coffee and enjoy throughout the day. Yes, it stays piping hot. :)

I really like using this when I do my workouts. It keeps my ice water nice and cold. It's easy to grip and also easy to carry. It's just the right size to keep my hydrated. I love using this and the color and design work too.

This Hydro Flask bottle is amazing. It have a very sturdy black handle that can be attached to a hook. We put water in this for my daughter for her soccer double header. After 5 hours it was still cold to drink. We were very impressed and happy.

This flask is amazing. I use it for work, on the go and at home. I mainly use it for cold drinks with ice. It keeps my drinks frosty for so long it is impressive. It is not too bulky so it is easy to take along. Lid seals well so no leaks. Cant wait to use it for hot cocoa in the coming cooler months.

I love the sleek look of this bottle. I put cold water in it at 7am on my way to take my daughter to school. 5 hours later at work and my water was still cold inside. Seems easy to clean and I like carrying it better than a plastic bottle.

I am a mail lady, I used this on a very hot day....this sat in my hot truck, and 5 hours into my day the ice was still frozen!! I love this it will keep my drinks nice and cold, when I need it the most

I love this bottle because it is double wall insulated and keeps drinks hot or cold all day long with no sweating involved. I can even leave it in my car while making geocery runs and it keeps ice from melting. The swivel top makes for easy carrying and you could even use a clip to put it on your backpack or bike through travel.

This thing is awesome really works keeps drinks cold for hours even on the hottest days very good product i would rank this as one of the best i recommend this product i will definitely buy again thank you

I have been using the Hydro Flask for taking my coffee on the go. It works great and kept my coffee warm for a long time. It's very high quality and easy to use. I also use it for drinking ice water. It worked well for both hot and cold beverages. I love the no slip powder coating. It makes it easier to grip. I also love that it's BPA free. I'm definitely going to buy this for gifts for family and friends.

I really fell in love with this flask after using it. It is super durable so it's great both in the office at work and outdoors on hikes. It has a nice sleek design and comes in many colors. It keep drinks hot or cold and works great!

The size is perfect, and I love the wider mouth. It makes it easier to clean than some other insulated bottles like this. It keeps my water nice and chilled for me all day which is a definite perk when you spend a lot of time outside in the southern heat. The color is vibrant and beautiful too. Very eye catching. I'm excited to see if it keeps my drinks warm in the chilly weather, but I have no doubt it will. I'd definitely recommend the Hydro flask, I love mine.

This flask did a nice job keeping my drink cold. I mostly use it to put my water in and keep it the way I like, cold. The bottle does not get wet from the condensation due to the insulation. It is easy to carry too. I take it with me to the gym and work. It does not even weight much either. The wide opening just gives the right space to put ice cubes inside of the bottle. I loved the yellow color of my bottle.

Let my active son try out this product-he found it to be totally awesome-his one complaint was that it would not get cold in the fridge, it seemed liquid had to be cold already-however whatever the temperature of the liquid, it kept it that way for long time

Wow, this water bottle does it all. I went on a hike for a few hours in the hot, hot sun and my ice water was STILL cold throughout the entire day! Literally, when I got home and set it down after my 5 hours outside in the 100+ heat, it still was freezing cold hours later. Amazing water bottle that keeps things cold and keeps things hot, FOR A LONG TIME! Also, and most importantly it has NO metal taste.

I was initially going to keep for myself. But my husband had other ideas lol. He is very picky with his cups, glasses or flasks. He said it works as directed and does even better. His coffee stayed hot longer and his cold drinks stayed colder.

I loved how it kept my coffee hot all day it was amazing it worked really well with hot products as well as cold products it kept smoothie cold all day as well this cup works perfectly for anyone I would recommend.

I love this hydro flask I think it might be the best that i've owned. I love that it keeps my drink hot or cold for hours. There is no condensation on the bottle that's what i like the most because i hate picking up something that's wet and leaking all over. I love that it's BPA-Free and Phthalate-Free! I love this and i highly recommend it.

I loved this water bottle!! I recently got a bicycle and this fits perfectly in the cupholder. It's easy to open, and kept my ice water icy for at least a couple hours. The color I chose was a teal blue, which was lovely, and the finish on the bottle was smooth and didn't scratch when I washed it. I loved it!

I am so thrilled with this flask and love taking it with me for all my outdoor activities especially on my weekend hikes. The liquid no matter hot or cold stays the temperature it should for a longer period of time. I received a free sample courtesy of Bazaarvoice Try It Sampling for my honest review.

I love this flask my son uses it for soccer practice and his water stays cold and with no sweat on the outside.It is easy to open and really made well. So if you are needing a great replacement for the other high priced brand give this item a try.

I love this water bottle. It keeps my water cold for hours, and the spout is big enough for me to put ice cubes in it. It is well made. I have dropped it several times, and it has not dented like some of my other aluminum bottles. Plus, I love this color!

This bottle was way better than I was expecting. It's sturdy, keeps drinks hot or cold and the color is nice. It's large in size as well. I would definitely purchase more of these bottles for my drinks.

I am incredibly impressed with the claims and real life tests I've put this hydro flask to! It certainly maintains a cold beverage complete with ice cubes (for me) over than 12 hours!! Of course not all the ice cubes were still full size, but 12 hours later, I still had ice cubes in it! I don't typically need something hot for too long, but it kept my coffe steaming until I was finished, whereas my coffee is usually cool by the time I make it to the end!! Definitely a great product!!!
