headwear to wear with yer flight-jacket ...

Gents,

well my first full winter in Europe is shortly ahead and i`m considering what kinda headwear would be a good / stylish completion for my flight jackets ...

I especially always liked that "Humphrey Bogart" style with wearing Fedoras aso

I already own several watch-caps but looking for additional stuff so please share whatelse you guys wear when on the road with your jackets

Saludos

Thomas
