Rayon From Bamboo Pillow Cases will make slipping into bed a definite treat. The porous composition of the rayon from bamboo fibers makes the fabric more breathable and temperature regulating than other fabrics. Relax with these smooth, clean feeling sheets. The pores are ideal for sensitive skin and will keep you cool and dry as the fabric wicks moisture away from your body. These Pillow Cases are antibacterial and resistant to odors.
