What makes the Insulated Sports Bottle ($20) from thinksport different from every other sport bottle on the market? Probably the bottle's double-walled, medical-grade stainless steel construction. The tough-stuff bottle is BPA- and epoxy-free so you get to enjoy your water without any potentially harmful side effects. It'll keep your H2O cold for hours on end without condensation buildup, too, so the only thing sweating on the treadmill will be you.
