I agree with John. The Hadron-S is an incredible hat, and would be my choice as well. It is a quality sewn hat, with an incredible headband.
His analysis regarding the hoods is spot on, in my opinion, as well. I have a Katabatic Gear Windom, and it is a VERY warm hat. I have camped down near 0, and the Windom is still a little warm, even though I was using a hoodless quilt. I would be well done by morning if I was using the Crestone.
I mostly sleep in the Hadron-S if a hat is required.
