Delighted.A ‘must have‘ environmentally and cost effective solution to getting water onboard.

My daughter loves it

Hydro Flask...where have you been all my life?! I am so thankful that my younger sister alerted me of this water bottle / canteen brand because it is out-of-this-world amazing! Like seriously, fill it with ice and water before bed...tons of ice still there in the morning and most of the day as I continued to refill it. This is a game changer, people. i would love to do a little test filling it completely with ice only and take photos throughout a 24 hour period. Perhaps an update to come ;)Ok enough over the top swooning...but seriously I have never seen something as insulating as this. I purchased it as a replacement to my camelbak (Eddy) water bottle with straw because the darn thing started leaking out the top on it's own and I couldnt fix it. It was terrible and left a huge puddle in my car holder, and when I picked it up it usually got me all wet on top of it :-| I was fed up and ready to invest in something that would last.Why I went with this one:Wide lid top - necessary if you want to buy the optional straw top. As someone using this throughout the day at work, in my car, next to my bed...I am not interested in constantly unscrewing the top. I will say that this new lid with handle is pretty great for long term storage and taking on a trip to be perfectly sealed and better insulated. It is said that the straw top doesnt make the insulation last as long. Lasts long to me, but as someone who occasionally camps for festivals in extreme heat - the longer the better and I will use whatever lid makes sense for the time. Nice to have options :)Size: I went with the 18 oz so it would fit in my car holder. Very important to me. The larger one seems awesome for situations where you need a lot more water, but not fitting in my car holder was a deal breaker. The smaller size choices are a bit disappointing. 18 oz isnt really very much and my camelbak was roughly 25 oz. I just wish it was more comparable.Color and coating: This blue is classic and neutral, but more colorful than the gray (that was what I was debating). It is true to color on screen! I kind of wanted the white as it was classy, but the down-to-earth, practical me was afraid it would get dirty easily. Im very happy with my choice. Its a bummer than this bottle style doesnt come in more shades, though. There was a different blue I really liked...and other styles have a lot more of the bright fun colors in the larger sizes. Is what it is. The trademark coating is a nice texture, durable, and its so amazing to have ice within it... but feel completely room temperature in my hand on the outside.** note: I read someone else state this and have observed the same. I have a VW Jetta with the plastic "claws" that retract for different sizing in my center area cup holder. It does seem to leave marks on this bottle (slight scratch marks) and that bums me out. I am having to put this in the door cup holder to avoid that.** Durability: Not that I wanted this to happen, but butterfingers me seriously dropped this right on my laminate flooring. Nothing happened to it! Not dings, not scratches. Impressive.What else can I say... this is totally a worthy investment to anyone wanting a high quality water bottle / canteen / liquid travel vessel. Lifetime warranty always shows the thought and confident put into a product. Love that you can go online and choose a donation charity of your choice out of a handful of non-profit organizations, with 5% of your purchase going to your selection. I always pick the animals charities and went with WWF.I'll be reviewing the straw lid separately but I will state here that it works GREAT and is exactly what I hoped for. NO MORE LEAKS!! Dont get confused and buy the knockoff by the way, I nearly did!!... if you are going to spend this much money, its worth getting the manufacturer's official lids.I LOVE MY HYDRO FLASK :D

Best quality and weight keeping hot/cold. Does not leak love variety of lids.

La meilleure des gourdes du marché !Garde très bien la chaleur et la fraîcheurUn must have

Hydro Flasks are fantastic - they keep my water icy cold for over a day, as advertised. I especially like the wide mouth, which makes filling them with ice easy. I also like that you can buy several different styles of lids - flip tops, with straw, etc. The colors are vibrant, they don't sweat, and there is enough texture in the coating to give them some grip. It's worth the price.Regarding sizing: The 18 oz. hydro flask is convenient because it fits into my car cupholder, whereas the 32 oz. size is too large to fit. However, I prefer the 32 oz. volume. Hydro Flask - if you are reading this - I'd really like it if you would make a 24 - 30 oz. version with the same diameter footprint as the 18 oz. version. That would be the Goldilocks size for me.Note: Be careful about dropping them on hard surfaces - Hydro Flasks dent easily.

The Hydro Flask works just as described. My husband is a Sport Official and uses this on a daily basis. He loves it because in hot weather it keeps his water the temperature he likes. It very durable. He ended up getting an additional lid with the straw opening with the finger loop. He loves it because he can use a clip to hook it to the fence and it doesn't have to be on the ground. No problems with leaking at all! He loves it so much we bought 3 flasks in different sizes. I use mine for hot coffee with the flip lid. It keeps the coffee hotter much longer than any other stainless steel container I have had. The company that shipped it was fast and thorough with excellent customer service, and it was available with Amazon Prime. The color/size selection was great an it came in 2 days! I would highly recommend this product.
