The Gel-Eze Under Bandage is made of a non-toxic gel material that fits snugly under a bandage. Simply chill it in a refrigerator to create a cool, soothing compress for aching joints or muscles, even on awkward areas like the knees and ankles. When placed under a saddle, the Gel-Eze pad absorbs pressure and creates a sturdy, non-slip surface for your saddle. The Gel-Eze is also washable, so cleaning it after use is as easy as scrubbing with soap and water.
