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

We took this water bottle to an amusement park recently. It was a super hot day and we were there in the heat for 9 hours! This bottle kept our water cold all day long! The ice did melt l, but I figure that's because we opened and closed it so many times during the day. Awesome product!

I got this flask. And I washed it then the next morning I used it. I put my morning coffee in it. And about forty-five minutes later. My coffee was still hot it wasn't cold. It was like I just had poured it into the flask. The size of the flask is the right amount for me. I would recommend this product.

I finally received my Hydro Flask and I couldn't be any happier with this product. This item will literally keep your cold drinks cold for a good twenty four hours and your hot beverages hot for almost 6 hours. I highly recommend this product!

I love the Hydro-Flask, it works really well with cold or hot drinks. I use it for cold drinks when I am outside working and for coffee to take with me when I go somewhere. Keeps cold drinks cold for at least 12 hours and hot drinks hot for at least 12 hours. Great Product.

I'm so glad I got this water bottle. It's the perfect size to carry my water in. It keeps my water ice cold for a long time. I forgot my bottle in my warm car for 3 hours and all the ice was still in it. If you want the perfect water bottle this is it! I also love the handle on the lid.

I've owned many flask but this one is really made with quality materials and heavy duty. The cold water i put in it stays cold the whole day even the flask was left in the car for almost a day on a 90 degrees hot temperature/weather. I so impressed with the quality and this is nie my go to water container when i go to the gym. Highly recommended product!

I really love this bottle! It actually keeps cold drinks cold for over 24 hours and hot drinks stay hot for 12/14 hours! I was really happy that it didn't have that metallic taste that some bottles do! This is great for on the go drinks! The blue color is very vivid! If your hands gets sweaty, you're still able to grip this bottle!

This has to be the best one I have ever tried keep it cold for hours even hot stuff just as long!! Nothing better then that very sturdy and takes a beating and holds up to falling sand it's made with good stuff!

I was super excited to receive this product because now I have something to keep my hot chocolate and my coffee to stay hot when I go to work. And in the summer it will keep my water really cold and I like that

This is one of the best bottles I have ever owned. It kept my tea steaming hot for hours and then kept ice in it for over 18 hours without it being completely melted. The bottle doesn't sweat which is one of my favorite features. It also has a nice thick loop handle that I can secure to my self or a clip on my side for when I'm exercising. I feel very confident that it won't drop or get lost. I like to clean it with some cleaning tabs so it keeps it fresh and deodorizes the very bottom but I'm sure a bottle brush would work just as well. I will definitely be getting these as gifts for people for the holidays.

I got this a few weeks ago because I loved the size, color and the Awesome features. I was looking for myself, but of course I'm sure my son will 'borrow' it from time to time and he's half my age! I think that says a lot about the design and look of the Hydo Flask 21oz standard mouth in a very nice looking white! Ita Gorgeous! It keeps drinks ice told for me because I'm a water or other cold water drinker most of the times but have had some coffee once that I was really surprised that this amazing Hydo Flask Kept so hot too! Awesome quaility and Great price, I'll be getting a few for Christmas gifts as well. I highly recommend it!

My daughter uses this for school. She loves it! She fills it up the night before and put it in her bookbag. She said it's still cold on the bus ride home. She absolutely loves it! Will definitely be buying more.
