[This review was collected as part of a promotion.] This hydro is awesome. Just like all my other hydros this one performs great. Cold things stay cold, my water has ice for 24+ hours even after I have refilled the water multiple times. I have not tried a hot liquid in it, but it is too warm to test at this time.
[This review was collected as part of a promotion.] My HydroFlask is the perfect size for me to hold and have in my work desk. The colors are cool as it looks like the colors dripped down.
[This review was collected as part of a promotion.] I love the size of this water bottle, since it fits all of the cup-holders for my cars. It also keeps my drinks well-insulated, and is very easy to take apart and clean. Best quality water bottles by far!
