Thermal engineering, attractive design, and a cozy carrying handle make this water bottle a cut above the rest. Built from stainless steel with vacuum insulation and copper lining, your drink will stay hot or cold for far longer than you'll need to drink it. The rubberized seal on the bamboo-accented lid prevents spills. Best of all, each bottle purchased helps fund the removal of one pound of trash from the world's oceans, rivers, and coastlines.
