Ello Cole Vacuum Insulated Stainless Steel Water Bottle with Slider Lid
So you won't be able to take the Ello Cole Vacuum Insulated Stainless Steel Water Bottle with Slider Lid ($18) into the airport filled with liquids, but once you get through security, you can store your favourite soothing herbal tea inside, and it'll stay hot for up to five hours. That's nearly an entire flight from New York to Cali!
