Plush on one side and silky on the other, the Huggaroo eye mask completely covers the eyes and blocks all light. Without its inserts, it is light as a feather. The two custom inserts instantly transform it into a heated or cooled weighted eye mask or sinus wrap. The hot patch insert heats up in just a few seconds in your microwave and provides soothing heat to your eyelids or facial sinuses. Unscented and aromatherapy versions are available. The reusable ice pack insert provides long-lasting cooling therapy and remains flexible even when chilled.
