Description

This advanced cup uses a double-wall vacuum-insulated stainless steel inner vessel within a collapsible silicone outer sleeve. It keeps beverages hot for hours or cold all day, a feature rare in collapsible designs. The inner steel cup is removable for easy cleaning, while the silicone shell folds flat. The ultimate choice for commuters, construction workers, or anyone who wants temperature control without carrying a rigid tumbler, blending premium performance with packability.
