You're not alone if you flip your pillow to find a cool spot! cooling fibers are woven right into the cover of this pillow and concentrated on the surface, to give you soothing, cool comfort and support. These special cooling fibers will never wash out - they're permanent and will continuously move heat away from your head and neck. The gel memory foam core adds even more coolness and gentle, cradling support. Sleep deeper, cooler, and better.
