Organic This travel tumbler is just what you need for all-day hydration. Take it with you to a high-intensity workout or on an extra-long commute to keep your drink cold for hours. The lid features a rotating cover with three positions: a straw opening, a wide mouth for chugging, and a full-cover top to prevent spills. The larger size even fits comfortably in your vehicle’s cup holder and comes with a rugged handle for carrying.
