40 oz Travel Tumbler

[This review was collected as part of a promotion.] Love the tumbler. Keeps my drinks cold, and very easy to clean. Bought the color Zinnia. Wish I could buy a matching boot in the same color for a cleaner look.

Cheap seeming

[This review was collected as part of a promotion.] I have really liked Hydro flask for a long time, but I feel like with competitors like Brumate who are making locking straw bottles with metal straws in them it’s really hard to compete with that. The Tumblr just isn’t what I thought it would end up being it was different in person to me.

Great product

[This review was collected as part of a promotion.] I absolutely love my new 40 oz Travel Tumbler! It keeps my water ice-cold all day (sometimes even overnight!) and hot drinks stay warm for hours. The size is perfect for keeping me hydrated without constant refills, and the handle makes it super easy to carry around. It fits perfectly in my car cup holder too, which is a huge plus. Stylish, sturdy, and practical — I honestly don’t leave the house without it!

Love this Travel Tumbler

[This review was collected as part of a promotion.] I have several of the 40 oz tumblers and I love them. I have tried different brands and this one is my favorite. The color Plum is stunning! These tumblers keep my ice tea cold even when it has been in the hot car for a couple of hours. Great product and love the colors!

Fits in my car cup holder!

[This review was collected as part of a promotion.] So many water bottles that I can’t bring with me because they fall over in my car. The bottom of this is amazing for car transport. The only complaint I have is the width of the straw. Would prefer it to be smaller!

[This review was collected as part of a promotion.] My wife likes this one even more than she likes the 32oz version. Outstanding.

Starlight day dream

I love these tumblers. They are for the most part leak proof and they are super cute, my sisters have the other brand that leaks all over so I got them these. They haven’t use the other ones since
