Beanie is soft and comfortable
I like how thin and comfortable the beanie feels. I would like to get a hat, however in order to fit properly I would need a hat that is cut for a woman. I hope you will offer female cut hats in the future.

Feels cool, though a bit snug.
It feels good. There's a sense of relief and a sense of cooling the head. It's nice and stretchy, though a bit too snug to wear a long time or sleep in - I have a larger circumference of the head than average.

Havn hat is great
Love my hat. I didn't know if it was working at all untill I took it off near a bunch of blue tooth broadcasting devices. It works. I work in a metal warehouse with 20 sets of paied blue tooth devices/routers etc. . I even sleep with it on sometimes. I am sensitive to these things more than most/anyone I know.
