Got a hot head? Need to cool off? Try our new cooling Sleep Mask with gel beads for soothing relief. Specially designed with a therapeutic gel bead layer lined with soft, plush fleece, this Sleep Mask+ soothes and comforts while blocking out light - to facilitate deep restful sleep. Our revolutionary gel bead formulation cools and soothes - and over time, harmonizes with the body's natural temperature flow to help prevent puffiness while you rest. FOR COOLING RELIEF: Chill in the refrigerator for an hour or put in the freezer for 5 to 10 minutes to desired temperature. Take out and gently place the soft fleece side of the mask over tired, strained eyes to relieve puffiness and swelling. [The gel side of the mask should be facing outward, away from the eyes.] Or place over hot spots to relieve over-heated skin. [Also great over forehead for temporary headache relief.] Provides soothing relief after a hard, stressful day. Adjustable velcro fastener to fit most head sizes.
