This water bottle has split personalities. One part water bottle, one part thermos, and one part martini shaker, it will more than get the job done. It breaks into three stacking sections for easy cleaning and storage, and all parts are BPA- and toxin-free. The silicone sleeve protects from dents, and the whole thing carries conveniently thanks to a strap made from recycled plastic. Fill it with water, smoothies, oatmeal, coffee, or even use to shake up your favorite cocktail. The bottle unscrews mid-body, meaning that cleaning and drying are as easy as swabbing out a normal household glass.
