The final product I chose to try was Ice Kap. When it comes to dealing with Cluster Headaches, no ice pack has ever felt better than the cold, tight compression of my Ice Kap. As a bonus, it is the only one that can also be warmed in the microwave.
The next wearable ice pack I decided to try was Migraine Hat. I quickly discovered that Migraine Hat was really great at preventing migraine attacks triggered by overheating.
My first introduction to wearable ice packs was MigraCap. Dreaming of a MigraCap for years, I finally made owning one a priority.
If you have Migraine, Cluster Headache, or any other headache disorder, you know the value of a good ice pack. They are the universal comfort measure for us all.
