Vikings love hats, and so should you. Hats sit on the head close to the brain, causing the brain to get excited and release endorphins. Hats also declare to all those who see them that the wearer is, in fact, a Viking, or, much more likely, wishes he/she was. There are many different types of hats, some more blatantly Norse than others.
This option is good for those who like to subtly express their aggressive Scandinavian tendencies; hockey is the Vikingest of sports.
A prime Viking hat for when it’s cold out. Viking mental euphoria is harder to achieve when the frostbite on your ears detracts your mind from wandering.
This one is obvious. Wear it to work/class.
