Who dat! I wore a New Orleans Saints knit hat while taking down the Christmas lights today. It was still very cold, but tolerable in the sun. This hat was the official sideline knit hat for the 2012 season. It is almost impossible to find. I did find the 2017 version at hatland.com. It is made of 100% acrylic on the outside. The inside is made of 90% polyester and 10% wool. Good luck to the Saints this weekend as they play the Panthers in the Superdome!
