Planetary Design Artemis Coffee Tumbler

Thanks to its double-wall vacuum insulation, this tumbler is designed to maintain your beverage's temperature for several hours. While performance can vary based on the starting temperature and how often the lid is opened, it is built to keep your coffee hot throughout a typical morning commute or hike.

Yes, the entire construction, including the lid and internal components, is crafted from BPA-free materials. This ensures your drinking experience remains safe and free from harmful chemicals.
