ASTONISHED!! 3 days and still has ice!!
5 Stars
ASTONISHED!! 3 days and still has ice!!
This product far exceeds my expectations!!!! I was skeptical that it would truly keep a product cold as long as indicated but I was incredibly wrong! When the Hydro Flask arrived my curiosity wanted to test their claims before I really started regularly using it. I filled the Hydro Flask with ice water the day I got it and I kid you not it still had ice on the third day! I was mind blown! The first two pictures I've provided show day one and the final picture looking directly in was taken on day three after consuming about half of the contents as I couldn't resist a few drinks.The Hydro Flask had absolutely zero condensation on the outside during any of those three days! I couldn't believe it! The texture is a powder coating and I think that's great as I don't fear that I'm going to drop it. As you can see from the pictures I provided, the color is vibrant and the blue looks great! The sport cap is a plus, it does not leak, and it makes for very easy use. It's not your typical spout tip either as it's a thick rubber. This might be a good thing for people who typically bite the plastic tip. I will say that the Hydro Flask is more expensive than other water bottles on the market from what I've seen but they are well worth the cost.Hydro Flask is designed and originated from beautiful Bend, Oregon which is where I was born and raised so I feel ashamed I waited so many years to try or buy or one. And although I live in Kansas City now, I love that I can have a little piece of home with me because I'm a sap like that. I can't wait to purchase another Hydro Flask for myself in the growler size. They'd make a great gift as well because who doesn't use a water bottle at some point. Bottom line, you will not be disappointed with purchasing a Hydro Flask!Finally, I am a paid consumer so I did buy this product with my own money. My review is genuine and my own. I know it's hard to believe because I'm so enthusiastic but the product is legit!

5.0 out of 5 stars Kicked a diet soda addiction... worth every penny!
Reviewed in the United States on October 4, 2018
I bought this product to help me kick a nasty diet soda addiction (I'm an 80's kid and was embalming myself with Aspartame). I can honestly say it was worth every penny. I've used other products (Kleen Kanteen, SIGG, etc) in the past, but those products sweat and left a mess on my desk at work and on me at the gym, warmed my water, and - in the case of Kleen Kanteen - looked unsightly as the paint peeled from the container. The Hydro Flask has allowed me to keep water cold at work and doesn't sweat, allowing me to drink cold and refreshing water all day at the office. It is also great at the gym for the same reasons. And it looks great! The matte finish feels good and the sports cap provides a nice seal. It is pricey, but I haven't bought a diet soda at work in over a month and a half (I was spending at least $1.75 per day on a 20oz bottle) so it has already paid for itself! I would highly recommend this product.
