福依蒂三明治盾保暖内衣 (Fuyidi Sandwich Shield thermal set) is a red, three-layer quilted top-and-long-johns set with a mid-height collar. An outer layer, a batting layer and an inner layer are stacked like a sandwich; the batting holds still air, and diamond quilting keeps it in place. It comes in the "Fuyun Shouhu" (福运守护) premium gift box. It suits parents who like a thick mid-collar layer, wear a loose coat over it, or are receiving it as a New Year gift.

In China, it focuses on technical-fabric thermal underwear and long johns made with care for older adults. In China, Foote Brother is operated by Guangdong Zhuoheng Investment Development Co., Ltd.
