The down jacket of the United States in the Winter Olympics is an intelligent thermal insulation material for skyscrapers. At the opening ceremony of the Winter Olympics, this dress of the United States team was not a down jacket, but a trench coat. It was a black technology costume designed by Ralph Lauren for the United States team and was worn at the opening ceremony of the 2022 Olympic and Paralympic Games.

Characteristics of American skyscrapers in the Winter Olympics

This windbreaker has two highlights. First, it is based on the concept of sustainable development, made of recycled polyester and made in the United States.

Second, it is also the black technology of this windbreaker. This windbreaker is equipped with skyscraper intelligent insulation material. This material is an innovative patented fabric, which can respond to temperature changes without using battery power or wired technology.

The special feature of this material is that it can expand with the decrease of ambient temperature, thus providing more heat insulation and warmth retention. When the ambient temperature rises, the intelligent insulation layer of skyscrapers will return to its normal thickness.
