福依蒂大红三盾保暖内衣（Fuyidi Red Triple Shield thermal set）
福依蒂大红三盾保暖内衣 (Fuyidi Red Triple Shield thermal set) is a bright red top-and-long-johns set with three tested functions: far infrared, antibacterial and anti-mite. Its knit-loop structure lets the neckline and cuffs open wide and spring back, so parents with stiff wrists or shoulders can put it on themselves. In China, red is traditional for the New Year and for one's zodiac year. It suits older adults who like red, and children looking for a New Year or zodiac-year gift for their parents. Foote Brother (福依蒂) is a personal protective equipment (PPE) brand that originated in the United States. 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.
