<p>Fewer refills equal more hydration, all thanks to the Owala 40oz Tumbler. But this is no ordinary insulated cup. Not only does it hold a whole lot of water, but it also has an awesome 2-in-1 lid. Want to sip? Use the sturdy, reusable straw. If swigging is more your thing, just remove the straw and sip through the spout. Another handy feature? It has an adjustable handle to suit left-handed and right-handed water lovers alike. The Owala 40oz Tumbler fits easily into most cup holders, making it the perfect car companion. Plus, it will never ask, "Are we there yet?"</p>
