This soft gel roll provides therapy for minor muscular and soft tissue cervical injuries. It has been designed to fit comfortably under the neck or lower back. The support roll is an ideal treatment for recurring neck and back problems. *NOTE: Some people have asked to return this item because they say is does not get cold like the direct application of ice. That is true, as there is a layer of Lycra between the coolant and your skin. Plus because most household freezers are actually too cold for direct applications this safeguards you against over cooling the treatment area.
