Good for after knee surgery
I followed the advice of somebody else and rolled up a small beach towel into a 'cigar' shape and then wrapped this around it because it is thin and  freezes hard.  It comes out of the freezer and stays the shape in which it was frozen for quite awhile.  This freezes very cold so I had to put a thin towel inbetween it and my husband's knee so that it wouldn't burn....  Good for after knee surgery.  The velcro helps it stay in place but we didn't use it after knee replacement because of the pressure it would place on the incision.
