The Helia mug made of 18/8 stainless steel keeps drinks cold for up to 17 hours and hot for 3 hours and comes with a glass straw.

Every detail of this vacuum-insulated 18/8 stainless steel tumbler has been carefully engineered to make your drinking experience as easy and enjoyable as possible. It's ready for any adventure while preserving the flavor of your beverage, so you don't have to compromise on refreshment on the go. A copper-coated double-wall construction keeps your iced tea, cocktail, or smoothie at the perfect temperature while preventing condensation from forming on the outside of your tumbler and thus preventing puddles on the table. Cold drinks stay chilled for up to 24 hours, and hot drinks stay hot for up to 4 hours. The Helia tumbler also includes a practical, durable glass straw and cleaning brush, allowing you to completely eliminate the need for disposable straws. Plus, you can rest assured that, like all SIGG products, it was designed with a special focus on sustainability and food safety. It's therefore both recyclable and free from harmful chemicals like BPA.
