There are water bottles, and then there is S'well, which takes to-go hydration to the next level by keeping hot beverages at temp for up to 12 hours, and cold ones for up to 24. The stainless steel BPA-free bottles come in 17oz. and 25oz. sizes—(the 25 holds a bottle of wine)—and have an opening just large enough to drop in ice cubes. They rinse out clean with no lingering aftertaste. In addition to keeping disposable bottles out of the landfill, S'well donates 10 percent of all sales to build safe and hygienic water sources in Africa and India through a partnership with WaterAid.—MH
