what about the striped ones? The black w/orange stripe looks cool, and the "current" one too.
I got the green striped one which I like. The green is more of a kelly green than the soft green they picture.
You can always get the solid black SmartWool skullcap on TE... that one fits right over your ears nicely and is a little more stretchy, which is good under the helmet. I plan to double up my green one and my SW black one when it gets really cold.
