Although the picture shown is a bare stainless steel exterior, the only mugs we currently have remaining are a dark midnight blue enamel exterior finish. The mug itself is still the same great leak proof travel mug design by Thermos, with the same great features, still stainless steel, only with the midnight blue painted exterior.

This Thermos tumbler is designed with a 360° drink lid, so you dont have to worry about pouring your drink down your nose, instead of in your mouth! Drink from anywhere on the lid, use as a right handed, or left handed coffee travel mug. Spill resistant sealable top, seal shut by turning rim to the closed position, drink by turning the rim to the open position. Turn it an extra notch, and the lid is now ready to be lifted off. A very unique design, and well thought out.

Thermos TherMax &174; vacuum insulation virtually eliminates temperature change by creating an airless vacuum space between two unbreakable stainless steel walls. The result is an insulation layer that performs better than almost all other insulation methods, excluding glass lined containers, which are for the most part, not suited for more rugged environments. Thermos TherMax &174;, Superior insulated containers that keep whats hot, hot, and whats cold, cold!

All of the double wall stainless steel lined Thermos Nissan products you will find at BaldMountainCoffee.com, are top of the line Thermos Nissan, which include the Thermos TherMax &174; vacuum insulation technology. We do not carry Thermos Nissan products that are insulated with foam. Although Thermos does manufacture other, less expensive lines of products that do not include their TherMax &174; technology, we carry only only Nissan Thermos products that DO include TherMax &174; technology, as we feel they are far superior to what else is offered.

As with all insulated beverage containers, we highly recommend pre-heating these units by filling them with hot water - or cold water, and leaving them sit for a minute or so before storing your beverage. This will greatly increase the amount of time your beverage will hold its temperature.
