Perfect Size
[This review was collected as part of a promotion.] As a working mom who frequents the gym, this is the perfect size. Helps me regulate my water intake and ensure I’m getting enough throughout the day. Typically only needs to be filled up twice a day. Love it!

Reef color is way off, but love the bottle
Unfortunately, the bottle is more of a purple color. Based off of the pictures on Instagram as well as the website, the reef color looked way more pink. While it is a pretty color, I was hoping for pink but it is definitely not. It is definitely purple.

versatility!
[This review was collected as part of a promotion.] This is great for long work outs. It stays full for hot yoga and the gym, unless its summer. Then the flask is good for just for hot yoga.

Just OK
With the amount of money we spend, one would expect to at least get a straw cleaner to come with it. Better yet, the older versions were better where you don't need the straw at all and it was just a lid.

Perfect Size for Hot Weather Hikes
This is the perfect size for hiking in hot weather- the HydroFlask keeps water ice cold for hours and the 64oz size is enough to last for longer hikes when the weather is very warm.

When will you bring back customizable 64oz wide mouth bottles? I have to replace my current customized one (dropped too many times and so many dents and paint chips) but I need something that stands out! These colors are so muted :(
