Its insanly warm for it's apparant thinness and for 10 bucks this is an insanely good deal and you would to put it frankly be insane not pad your order out with it.

And for the rest its a beanie, it doesnt itch and the inner 3M fabric does its job and makes it extra comfortable.

As described, simple but well made and does the job. You do not need anything fancy. Good bit of kit.
