Mary Ann R.wrote a review of Hydro Flask 21oz. Standard Mouth Water Bottle on March 27, 2013
This water bottle rocks. It truly keeps the hot things hot and the cold things cold, without any aftertaste, for hours. The 21 oz is the perfect size for me. I have it beside me in my car all day, and my water is always the temp I filled the bottle with. It never disappoints.
Buy this water bottle - you will not be disappointed.
