Keep your drink at its ideal temperature throughout the day with the Zojirushi Stainless Steel Mug. The mug features vacuum insulation and a design that allows you to drink beverages straight from it. Even though it looks like other travel mugs, the Zojirushi mug provides better heat retention thanks to its tight-fitting lid. Plus, you can store it in your purse or bag without worrying about spills. Additionally, the Zojirushi mug maintains your drink’s temperature by removing the air between the two stainless steel layers that form the body. Without any air, the temperature from the other side doesn’t transfer so you drink stays cold or hot for hours. The mug offers a 16-ounce capacity and comes with a wide mouth opening for easy drinking.
