The Shelter YETI Rambler is a YETI stainless steel tumbler with a MagSlider lid, in red with the Shelter Design Build logo or black with the Shelter Institute logo.
Double-wall vacuum insulation keeps coffee hot and water cold from the first cup to the last, and the 18/8 stainless steel resists punctures and rust. The magnetic slider on the lid opens and closes easily, though it isn't leakproof. It goes in the dishwasher.
