Material: Stretch fabric. Gel 360 HEAD AND EYE COVERAGE: This headache cap provides complete head and eye coverage, covering almost your entire head from front to back, to relieve the stress of migraines and tension headaches while you rest comfortably and relaxingly. WEARABLE MIGRAINE RELIEF CAP: Our head cooling pack can be worn two ways, covering your eyes while you rest and relaxing your puffy eyes and tired head, or just covering your head and relieving headache migraines without interfering with your normal work. UPGRADED CRAFTSMANSHIP AND MATERIALS: We have used a special cut form to avoid the common threads and burrs found in textiles and have reinforced the edges of the ice pack cap to extend its life. In addition, we've added 20% more reusable ice gel than regular headache migraine relief caps to release head pain, eye swelling, bruising, swelling and pressure. SUPER FLEXIBLE AND COMFORTABLE : Features a one-piece design that makes it easier to wear. With stretchable gel padding that is very flexible when frozen. So it is very soft and perfect for people who don't like to wear hard ice packs on their head.
