Customer Reviews Hydro Flask 18 oz Standard Mouth with Standard Flex Cap

This is like 6th hydro flask, I love all different color options. I used it to keep my baby's water warm for her bottle when I'm out running errands on the weekends even if i forget to dump the water when I get home the next day it's warm. Also, I use it to keep my water cold on hot summer days, i usually fill it up at 9am and still

Excellent product. Very Easy to clean. Great quality!

This bottle is terrific. Great size and keeps water cold for hours.

Perfect size for daily school/sports use. My DD loves it!

Love the color and lid! The lid is super because you can swing the strap to the side and stand it on the outside of the top.

I bought 2, an 18 oz and a 21 oz. Both standard mouth. I love them both. They keep my drinks cold.

It keeps things cold forever! I have 6 of these and am a big fan.

I love the hydroflasks and i have bought many of them. The lids aren't great though. I am always having to replace them. They leak or completely break. The only other complaint I have is one time of dropping a hydroflask and there is a guaranteed dent. For such an expensive product I would expect more. I keep on buying them but I may need to make a different choice.

The standard mouth means you can't fill it up to the top.
