The Road Trip Tumbler is designed for great taste with a ceramic-lined interior that protects beverages from metallic taste and smell. So go ahead and fill it with your favorite green juice or iced coffee and enjoy great flavor with every sip. Our uniquely designed multi-function lid allows you to drink with two settings, open mouth or with a straw (2 straws included). Once you're finished, just close the locking tab, or remove the straw for leak-resistant transportation. The Road Trip Tumbler features a comfortable handle, dual threading for left and right-handed use, and is intentionally designed to fit in most cup holders. That means you can take your tumbler anywhere with you, and always have quick and easy hydration within reach.
