Simple Modern Collegiate Officially Licensed Insulated Drinkware Scout Mug has a double walled exterior with a vacuum between the walls. That means the temperature of a drink has no medium for the heat or cold to transfer through. Your drink will stay as hot or cold as possible. Filled with ice or hot water, the drinkware will never sweat or get hot to the touch.
Simple Modern insulated bottles are made of high-quality food-grade 18/8 stainless steel metal and are BPA free. This steel is highly rust resistant and does not retain odors or flavor. Hand wash only.
The exterior of the vacuum sealed area is dipped in copper for added insulation. Copper reduces the transfer of temperature, adding even more insulation to your bottle. The BPA free stainless steel lid is also insulated against heat transfer. The exterior will never sweat. Forget about about getting water on your important papers, rings on your table, or a watery mess in your bag.
