Multi-functional and high-performing fabric comprising a first layer of yarns woven to form the fabric wherein the yarns comprise at least one unitary graphene-based continuous graphitic fiber comprising at least 90% by weight of graphene planes that are chemically bonded with one another having an inter-planar spacing d.sub.002 from 0.3354 nm to 0.4 nm as determined by X-ray diffraction and an oxygen content less than 5% by weight. A majority of the graphene planes in such a continuous graphitic fiber are parallel to one another and parallel to a fiber axis direction. The graphitic fiber contains no core-shell structure, has no helically arranged graphene domains or domain boundaries, and has a porosity level less than 5% by volume, more typically less than 2%, and most typically less than 1% (practically pore-free).
