From the designer:

“I saw “The Life Aquatic” on Tuesday night. There’s a lot of great knitted stuff in there, but I became obsessed with the little red beanies all the team Zissou members wore… so I made my own!!!!! yay! mine is like the one Klaus wears because it has a pom pom on top- i didnt know how to make that extra little bunch of fabric like other guys have (i’ve decided to call that a ‘hair reservoir’).“
