[This review was collected as part of a promotion.] I love my hydro travel tumbler . It’s one of my favorites. I love the style and how convenient it fit in my cup holder of my car. Also the colors!!! I’m getting hooked ! I find myself drinking more water using my tumbler.

[This review was collected as part of a promotion.] I have several but not ones that fit in my cup holders. Love the colors and the fact that these are dishwasher safe!

[This review was collected as part of a promotion.] I love having icey cold water all day long even if my hydro flask has been sitting in my hot car in the Austin sun. I bought one, and now had to buy two more since they are so cute and colorful and of varying sizes and types.

[This review was collected as part of a promotion.] I highly recommend this 40 oz. Travel Tumbler.
I take this tumbler everywhere. It keeps ice frozen for 12+ hours.

[This review was collected as part of a promotion.] I love how long these keep drinks cold. If I set it on the counter with the remaining ice after I have a drink, there will still be ice in it a day later.
