Different models or fakes?? I purchased my original Hydro Flask from a local hunting shop near me. I fell in love with it and soon my whole family was stealing mine! So I decided to buy them all their own for Christmas this year. I am a little disappointed because the logos are different on the ones I purchased off from Amazon compared to my original one. My original one still has ice in it after 24 hours but the new one I bought barely have ice after a couple hours…. I’m wonder if there is different models or something…

I’m returning both of mine and buying direct on these.

Darn $$$$$ water bottle, but it’s great. Originally, I couldn’t justify spending this absurd amount of $ on a water bottle.

Initially he was like “oh, gee, um, a water bottle?!” But then he spent all day out in 90+ degree weather and came back incredibly enthusiastic, going on & on & on about how amazing it is. So I got another one for my teenager, who needed a water bottle, but doesn’t pay much attention to mundane things like this. He, too,…
