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. The ceramic-lined interior protects beverages from metallic taste and smell, makes it easy to clean and doesn?t absorb any flavors. 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.
