Delta Insulated Mug 16oz - Double Wall Vacuum Stainless Steel Travel Coffee Tumbler with Lid, Leakproof & Sweatproof, Keeps Drinks Hot/Cold for Hours - Perfect for Office, Commuting, Camping & Outdoor Activities

This mug features a groundbreaking advancement in thermal insulation. We 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.
