12 oz travel mug

These products are listed with a 12-ounce capacity (often shown as 12 fl oz US) — listings commonly state the cup holds 12 ounces.

Retention varies by model: some insulated 12 oz mugs advertise hot retention up to about 6 hours and cold retention ranging roughly from 12 hours up to 24+ hours.

Care instructions differ by model: many recommend hand-washing (especially for lids), some are top-rack dishwasher-safe, a few list dishwasher-safe lids but recommend hand-washing the cup, and a small number note dishwasher- and freezer-safe use.

Examples include double silicone gaskets for 360° sealing, watertight flip-straw designs with valves, screw-on lids with valves, and slider closures that seal when closed.

Common terms include "double-wall," "double-walled," and "vacuum-insulated," often combined as phrases like "double-wall vacuum" or "double-wall vacuum insulation."
