Wrong size

[This review was collected as part of a promotion.] Ii read the details multiple times and it said it would fit on my wide mouth cupIi read the details multiple times and it said it would fit on my wide mouth cup. Of course when I got it, it did not. The description online needs to specifically say which cup it fits. So disappointed. I am sure it is a great lid, just does not fit my cup. Too much hassle and expense to return so a total waste of $. Of course when I got it, it did not. The description online needs to specifically say which cup it fits. So disappointed.

A Keeper

[This review was collected as part of a promotion.] I've used a lot of brands and Hydro Flask is my favorite. I use stainless steel water bottles and this one is substantial. It fits in a cup holder. It's easy to clean.

The Perfect Size

[This review was collected as part of a promotion.] I was looking for a bottle that wasn't too big, or too small, and I found it. This bottle is the perfect size for me to take everywhere. The etching looks great that I added. Definitely worth the price.

Nobody Does It Better - Hydro Flask!

[This review was collected as part of a promotion.] Design, Quality and Function are outstanding. 21 oz better for smaller hands and not heavy to hold when filled with ice. Keeps liquid cold 24+. Love the color choices with options to monogram(Text) or a Graphic. Love my Graphic (Love is all Around).

Great for on the go

[This review was collected as part of a promotion.] I love the 21oz standard mouth flask for when I’m on the go. I currently use it for my 5 month olds formula when I’m out running errands. Keeps it the right temp all day so it’s easier for me to just pour her a bottle.
