content: Once we finally rec'd the correct item ( orig order not from this company, so no reflection on them).....my husband loves it. He uses it for cold therapy only: his preference, not that it does not work well for that. So I can only tell you for cold therapy it rocks. I did not think it was cold enough for my lower back, but it is not sculpted for that. He loves its flexibility and states it is cold enough. He uses it for chronic neck pain. Just wraps it on his neck and goes to bed: it has a Velcro strap to keep it in place. Almost like having a neck pillow on, but not as bulky. FABU product!!!
