This travel mug is designed to make staying hydrated and maintaining a healthy lifestyle wherever you go even more appealing. A double walled, vacuum-insulated body is made of 18/8 stainless steel which insulated cold drinks for up to 24 hours and hot for up to 6 hours, keeping them as fresh as any "just-purchased" option.
The double wall also means the exterior will stay a comfortable temperature to hold, while a sturdy Tritan lid easily slides open and closed for one-handed drinking. This travel mug features an eye-catching illustration from the book Kunstformen der Natur (Art Forms in Nature), first published in 1899 by biologist and naturalist, Ernst Haeckel.
