This headgator is snug and thin. I didn't want anything too bulky, and it does fit easily under the hood of my parka and keeps out the worst of the wind. It's also water resistant, so melting snow tends to bead and roll off and not soak in.

But it's in fact so tight that it starts to choke me when I try to pull it under my chin, which limits the numbers of ways I can effectively wear it. I'll still try it again next winter, though, and hope the fibers will relax enough for the fit to remain snug but not quite as uncomfortable.
