So good! I lost my last hydroflask at a club... So I decided to size up and love it so much. It's a lot more compact than I expected and keeps my water cold or warm all day!
[This review was collected as part of a promotion.] My air went out in my house in 105 degree heat. The repair man wasn’t coming for two days. It was time to see if the Hydro Flask was all that and in my eyes the new Hydro Flask with a screw on top does do what it advertises. My water stay ice cold with ice all day. I took the Hydro Flask to the park, work and may have left it outside when gardening (I definitely did for over 20 hours in over 100 degree heat index) and everything time I took a drink the water was cold. Most of the time the ice was in there for hours in the heat (I can say it kept nice ice cold water with ice for over 10 hours when camping for sure). The blue color gets many compliments. The best thing for me is it is DISHWASHER SAFE! I just need that for myself to feel it is really clean. After at least 15 washes in the dishwasher, it has not faded in color and looks as good as the first day I received it. I have also used the Hydro Flask for hot coffee at work. I must have have hot coffee even during the summer. The Hydro Flask kept my coffee hot for at least 5 hours. The flask is also made out of stainless steel, BPA, toxin free, and has a limited lifetime warranty.
