Tried one of these at physical therapy. Bought two that night. These are great: heavy, hold temperature, and conform to your body on their own. This size is just a little too big for a knee, but works well for a swollen knee after surgery. I used to hate icing with just a plastic bag and ice cubes. This pack provides a smooth, even cooling effect that is soothing, without the freezer burn of a bare ice cube. Even for breakthrough pain, I've found that this is quicker than my prescription painkillers (nasty stuff, those). The extra large is a little awkward. Pre-surgery, it was a little too big for a knee. Post surgery, its about right to do a 180¡ã wrap with the long axis parallel to my leg. Anyone smaller than 6' would probably want the Large instead,
