Zojirushi SM-ED Stainless Vacuum Insulation Bottle SM-ED30


The 10 oz. stainless mug from SM-ED is perfect for carrying a serving of morning coffee or iced tea while running errands or traveling. Like other vacuum insulated mugs of the brand, Zojirushi SM-ED30 Stainless Mug is artfully designed to achieve a stylish aesthetic while keeping the bottle compact in size and minimal in weight without budging from the quality and efficiency of the materials used.

The vacuum insulation technology used in these series work to keep the temperature of the beverage at a constant for hours by completely removing the air from in between the two layers of stainless steel that make up the walls of the mug. By doing so, a vacuum is created disabling any heat from travelling through air thus creating an advanced way of preserving heat. To strengthen this retention of temperatures, the insulated products feature a layer of copper or aluminum which help reflect the heat. The insulation of the body of product is aided by an airtight, insulated lid. The heat retention achieved through this technique helps keep the hot beverages still hot (rather than lukewarm) and cold beverages cool (rather than room temperature) for hours after filling when compared with products using either foam or double wall insulation.

The twist open lid snugly fits the mug creating a barrier for any accidental leak while the mouth piece that’s fitted at the mouth of the mug can be removed for drinking comfort. All the surfaces that come into contact with the beverage, including the lid are manufactured using BPA-free materials to assure safe use.

Tip: It is recommended to pre-heat or pre-chill the mug with hot water or ice to help them preserve the beverage’s temperatures longer.
