The Stanley 1913 IceFlow Flip Straw Tumbler in Cream makes it convenient to keep water close throughout a busy day. Its built-in flip straw lets you sip without taking off the lid and snaps closed between drinks. Double-wall vacuum insulation helps keep drinks cold for hours, while the folding handle makes it easier to carry to work, the gym or on a commute. The base is shaped to fit compatible vehicle and exercise-equipment cup holders.
