I suffer from chronic migraines, and once had a month long cluster headache that I am now medicated to prevent. During my month of suffering I had ordered the normal version of this, and loved it. I don't have migraines as often anymore, but I sleep with this EVERY night, I don't even put it in the freezer often unless I have a headache, it's just SO nice to sleep with.After about a year of straight use I just bought it again, because it's SO worth it. After about 6 months of nonstop use it does fray a bit and stretch out, but it is still completely usable and comfortable. And it's probably not meant for nightly wears and yet held up incredibly. Even if you don't have headaches and just want something super comfortable to cover your eyes and ears at night I highly recommend this product!!I have a small head, always have, and it fits fine. My brothers have larger heads and have tried this on and it fits them fine as well. It's made of stretchy fabric, so honestly I'm sure it's a one size fits all situation.I also have sensory issues, so if you do I'll describe this as best as I can - Slightly squishy but not in the "makes noise and feels yucky" sense but more the "soft cushions under leggings" sense. It doesn't bother my sensory issues, but I know that varies for everyone.
