It's not a Santa hat!

The real significance behind the "santa hat" we've seen B XVI in lately. Little bit of papal trivia for y'all. :) From Yahoo!:

Pope Benedict XVI resembled a clean-shaven Father Christmas when he donned a red velvet hat with white ermine trim to face a winter chill for his weekly general audience.As temperatures hovered around nine degrees celsius (48 degrees fahrenheit) thousands of pilgrims who gathered in the square were treated to the rare sight as the 78-year-old pope arrived for the audience in his popemobile, waving to the crowd. His secretary removed the hat when the pope sat in his throne for the beginning of the ceremony, for which his headwear was the usual round zucchetto cap. No pope since John XXIII, who died in 1963, has worn the traditional Camauro in public, though its use by popes goes back to the 12th century.
