Whether you're going car camping, headed to the beach, or an outdoor event, this mug -- the Yeti Rambler -- can keep cocoa and coffee hot or water cold for some four to five hours or so. A lot of people may already be familiar with the ever popular Yeti coolers that are over-engineered in a good way. (No wonder they're so pricey.) The mug runs around $24 and it weighs some 14 ounces, not light. But any mug that performs so well -- and looks good -- may be worth it. It's comfortable in your hands, has a wide mouth so it's perfect for soups, stews or chili, is durable and can be easily cleaned in the dishwasher. It's made from heavy gauge steel and has a double-wall vacuum insulation.
