I have had spine surgery four times, so I know ice packs quite well. This is a really good one. It is flexible when you pull it out of the freezer, but just as cold as the ones that are stiff. It¡¯s big, too, so it covers my lower back and the back of my hips. I am probably going to order another one if I have spine surgery again, just so I can always have a cold one in the freezer.
