The BrüMate MultiShaker Blender Shaker Bottle is a great gift for anyone who wants to stay hydrated while keeping your liquids cold or hot all day long. I have this bottle, and I love it! It has a built-in, removable agitator acts as a barrier that keeps ice from hitting you in the face when you take a swig. It also is perfect for mixing up a protein drink after a workout. The agitator also acts as an infuser, so you can also put in some fruit slices to flavor your water and it keeps it in the bottle when you drink. The super high-quality magnetic flip-top lid is super satisfying to use and is completely water tight. It comes in lots of colors and patterns, and has a convenient carry handle.
