The fit, feel, and package choices with discounts for 2nd add ons are great. I am on my 3rd hat an 1 beanie. I keep these every where. One in the car one in the room and one on my head. Ha ha.

Pleasantly suprised.
I really have been pleasantly suprised. I wasnt expecting a difference but I definitely wake far less frequently, I am now sleeping through the night and I am noticing that I am more refreshed when I wake.

Yes, to the cap
I highly recommend the cap. I really has helped with flying on an airplane. I was able to relax better and nap on the airplane.
