From the manufacturer

If you’ve ever wanted to take your favorite coffee cup backpacking, your wish has been granted. Crafted from ultralight titanium, the Titan Double Wall Mug’s insulated design provides exceptional heat retention so drinks stay warmer longer. A durable BPA-free plastic lid helps keep the heat in and splashes to a minimum. You may just find yourself reaching for the Titan at home too. Plus, the Titan Mug nests inside the Titan Kettle 900mL so you can pack your bag efficiently.
