Available only from Hammacher Schlemmer, this is the circulation improving throw made from a patented technology clinically proven to temporarily increase blood flow and promote restful sleep. The throw's performance fibers are interwoven with strands of Celliant, a thermo-reactive mineral matrix that converts released body heat into therapeutic infrared light that is reabsorbed back into the skin. Studies conducted by the University of California Medical Center, Loyola University Medical Center, and an independent Houston-based research firm showed that the safe, invisible infrared energy generated by the fabric in sock, glove, and shirt form temporarily promoted increased local blood flow. Optimized blood flow — in addition to helping regulate body temperature — has been a reliable method for decades to help increase comfort and promote better rest. With up to three-letter monogramming in navy thread for ivory; black thread for gray. 70" L x 60" W. Ivory or Gray.
