Carry more of your favorite drink from morning to night with this Ozark Trail 40 oz insulated stainless steel tumbler. Double-wall vacuum insulation helps keep beverages cold for up to 24 hours or hot for up to 6 hours, so it can stay by your side through long drives, hikes, and busy workdays. An integrated handle gives you something to hold onto while you are on the move, and the spill-proof lid with a built-in straw makes it easy to sip without unscrewing a cap. It's also designed to fit in most standard car cup holders, so it can travel with you from home to the road.
