The term 'winter roof-rack item' can be summarized as a SKI, which is a three letter word. Skiing is a popular winter sport that involves sliding down a snow-covered slope on skis, which are long, flat runners made of wood, plastic, or metal. Skis are typically attached to the feet with bindings and are used in conjunction with poles to help the skier maintain balance and control. Skis are often used for recreational purposes, such as downhill skiing, but they can also be used for transportation in snowy conditions.
