I use size L Shiv/Envore with earflaps gone and beanie underneath.
smith circut helmet.
looks steezy, stays warm, lasts forever AND works perfectly with cbars, check prof. pictures for an idea.
my 2 cents
This is my exact setup:
And a black hat
I used this setup last year and i'm doing it again this year
