ColPaC Gel Filled Cold Pack, 23in Neck Contour

My wife has chronic back problems after surgery. These ice packs are superior to anything I've ever used before... in fact, when she goes to the hospital for followup procedures once or twice per year, we bring our own cold packs in case they don't have them. Some hospitals have these great packs, but others do not. We keep two in the freezer so they can be rotated out... we may add a third to help with lag-time... on bad days, the second one has sometimes warmed before the first one has completely re-frozen. If you need a cold pack, these are the ones you want. They're so much better than anything else out there it's just no competition. The large size of these is excellent as well.

Unlike some other packs, this baby gets ICE cold. It doesn't stay cold super long, but it does work and it's pretty robust. I just wish they made one with velcro to hold it in place. And I agree with the other reviewer, it can get a little wet - in the freezer an icy layer builds up, which in turn melts on your shirts. So wipe it down before use.
