About this product Headache and Migraine Relief - Finally, drug-free relief for headaches and migraines that actually works. This migraine ice head wrap provides 360-degree coverage, completely enveloping your head in an icy cocoon of coolness and compression. Cold or Hot Therapy - The form-fitting gel migraine hat can be frozen for cold therapy or microwaved for heat therapy. It directly targets problem areas such as temples, forehead, sides, back of the neck, and eyes. Soft and comfortable without unnecessary pressure. One Size Fits All – The one-piece wrap design provides soothing, positive compression to relieve headache and debilitating migraine flare-ups. The natural fit of the migraine hat allows you to relax without worrying about it slipping off. Rapidly Freezes and Stays Cold Longer - The medical-grade inner gel material freezes in just one hour and stays cold longer than traditional ice packs. Be sure to purchase two or more if you need longer, continuous relief, so you always have one ready to use and another on standby. Dark Light Block Eye Cover - There is a built-in eye ice pack section at the bottom of the migraine cap to target swollen eyes and cluster headaches that are localized behind the eyes. The light-blocking design provides a blackout effect without closing the curtains.
