Review: Wet works - I only buy HydroFlask products. I have many different versions and I love them all. They retain heat well or maintain coldness well. They are leak resistant. I love the design of the cap with the handle. The lid is robust and well made. They come in a multitude of colors. I favor the 20 oz water bottle size. It’s a functional product. I love the icon symbol too. I recommend any of this company’s products.
Review: Great water bottle for a day out - I have many pieces of Hydro Flask now. They are well made, keep water cold all day, and reasonably priced. I got this one because the opening is large enough for ice cubes and still easy to drink out of without spilling. I have the 21 Oz which fits nicely in my car cup holder. It is sleek looking and the little handle on top is handy.
