A reusable bottle won’t be at the highest of your packing list, and that we get it—as very much like we all attempt to reduce plastic waste reception, it’s even harder to try to while on the road. But as long as the typical price of a bottle at the airport is on the brink of five dollars (and beverage is that the key to beating jet lag) it is time to start out packing a reusable one in your carry-on, for the sake of your wallet, the environment, and your sleep schedule. Below, the simplest travel water bottles for staying hydrated while on the go, from silicone-covered glass bottles to insulated chrome steel tumblers.

Perfect for: the planning lover

Corckicle makes a number of the simplest chrome steel canteens out there—this model, like others by the brand, promises to stay drinks cold for up to 25 hours (seriously), or hot for up to 12. And miraculously, it manages to try to so without sweating or looking as industrial because it should given how hard it works. Corkcicle’s canteen comes in every shade of the rainbow (plus a number of metallics), but our favorites come from the collab with L.A.-based design brand Poketo. With bright colors and abstract designs that differentiate it from your average heavy-duty canteen, they appear so good it’s hard to believe they’re as functional as they’re.

This minimalist tumbler from Kinto does double duty on hot and cold liquids, maintaining their temperature for 6 hours. Though it’s made from chrome steel, it comes during a mixture of chic muted neutrals and bold basics like dusty rose and marigold, meaning you won’t mind asking that hip Parisian barista to refill it for you. At about 16 ounces it can fit an honest amount inside, but the profile is a smaller amount bulky than other bottles like it—and because of a screw-off handle, you’ll further reduce the profile to form it even easier to pack and tote around
