A viscose fiber comprises a fiber body including a regenerated cellulosic material and a plurality of microcapsules dispersed in the regenerated cellulosic material. The regenerated cellulosic material is derived from an organic plant material and the plurality of microcapsules containing a phase change material has a transition temperature in the range of 0° C. to 100° C., the phase change material providing thermal regulation based on at least one of absorption and release of latent heat at the transition temperature.
