I was skeptical but ordered anyway. The hat does what it says. It is lightweight and while it is still hot out and I am still hot, the hat does seem to make it tolerable. My head does not get wet, or sweat. When I took the cap off, I still had hat head, but it was not wet hat head. If anything the top of the hat dried out too quickly. I used it on a recent vacation out west in 107 degree weather. The only complaint I had was I thought the back opening was a bit too small. I am used to carrying my cap around my wrist through the back when not in use, but the opening was too small and I was not able to put my hand through it.
