Lululemon's proprietary fabrics are specifically designed to enhance performance and comfort for athletic and active wear. The fabrics listed in the correct answer, which include Nulu, Nulux, Luxtreme, Warpstream, Luon, and Everlux, are all developed with unique properties to cater to various workout needs.
