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.
