Coffee or beer? Both suit the Insulated Tumbler just fine. Made from durable 18/8 food grade stainless steel, the 16oz (473ml) Insulated Tumbler is designed to last and travel safely where glass can't go. Double-wall vacuum insulation and electropolished stainless steel don't impart or retain flavors. Comes with press-fit Tumbler Lid (NOT leak-proof).
“Cup of coffee that lasts! I am outdoors for most of my day. Coffee really does stay warm for hours. Only complain is lid doesn't have slide across piece so fluid spilled out when i hit a big bump.”
