For over 75 years, Battle Creek Equipment Company has provided professional-quality health and fitness products to help you "Feel Good All Over." The Battle Creek Thermophore Moist Heating Pad / Pack electric fomentation unit was developed to conveniently provide moist fomentation treatments whenever moist heat is indicted. The Thermophore Hot Pack has a special tightly-woven fleece blend cover which retains moisture from the air. When the unit is turned on, the surge of heat into the cover moves the moisture from the heated fleece blend to the cooler body tissue.
