Anyone who has read the books or watched the TV series knows that when it comes to the Starks, they are obsessed with winter. And not for the fun reasons like snow, xmas and doing it in front of the fire.
Nope they simply like to know that its coming. Just so they can be right. Well with this shirt now you can be right too.
Join the Starks in their winter obsession by informing people just what time it is.
