Patriotic (20 or 30 oz.) Tumbler
The Tumbler Warehouse Tumbler is made of 18/8 kitchen-grade stainless steel, has double-wall vacuum insulation, and No Sweat Design which means that you've got one heavy-duty, over-engineered cup on your hands. It'll keep your cold drink cool well past sundown or your coffee nice and hot throughout the morning.
