This mug features a ground-breaking advancement in thermal insulation. STS use an integrated molded Polyurethane sleeve that insulates the liquid inside the mug, unlike double-walled mugs which only protect your hands but don’t keep your beverages hot or cold. Excess liquid flows back into the sipping hole because of the concave design of the lid.
