Magic Gel Migraine Ice Head Wrap - Real Migraine & Headache Relief | The Original Headache Cap | Cold, Comfortable, Dark & Cool; Endorsed by Physicians, Loved by Thousands - Purple

I'm not a huge fan of these. It gets VERY cold, more so than a solid icepack block thing due to the very high surface area but it also loses its energy very very fast, so I find myself trying to find a comfortable way to wear it without the freeze hurting too much and then suddenly it's warm and i have to go get a new one I prefer one of these: https://www.amazon.com/Magic-Gel-Comfortable-Physicians-Thousands/dp/B07DG2Z1NHhttps://www.alibaba.com/product-detail/Sport-Injury-Ice-Bag-Natra-Cure_1601469386203.html
