RELIEF, AT LAST: Imagine finally leaving the house to do the things you love — without the burden of migraines, tension, or cluster headaches. That's the case for thousands of people who have discovered the original IceKap. And while it’s not a miracle, it IS the patented therapeutic, drug-free headache relief the world loves..STAYS COLD FOR UP TO 3 HOURS: Icekap comes with 5 Therapy Grade Non-Toxic Gel Ice Packs. These last longer than others (Up to 3 hours!) and remain soft when frozen, so they can easily conform to your head. And they can be heated OR cooled for your needs. IceKap lets you choose where to put ice packs for targeted relief, or use every available "ice pocket" for complete coverage..PATENTED PRESSURE THERAPY: IceKap is the only headache relief cap supported by the National Children’s Cancer Society and recommended by MD’s. It's the first of its kind to incorporate an occipital tension band, which compresses muscles on the back of your head for science-backed relief. With soft micro-fleece and a unique hair loop, it's so comfortable that you'll melt into the fabric..TARGETS THE ROOT OF YOUR HEADACHE: Unlike other headache hats, Icekap features a unique "back flap" for full coverage of the occipital region — where many headaches originate. Wear it backwards as a migraine mask, and the flap covers the eyes and sinuses. Icekap Migraine Relief Cap is fully machine washable and is crafted from polyester/spandex with a cozy mesh and fleece inlay..THE “PERFECT FIT” PROMISE: To help you get the perfect amount of compression, we offer Cold Caps in 4 sizes. We highly recommend taking 1 minute to measure your head before choosing your size. For a perfect fit, measure the largest possible distance around your head. If you measure on the half inch, we recommend moving up a size. Don’t have a measuring tape? Use string and a ruler…and if your Icekap doesn’t fit, just contact us to exchange it!
