The Purr-Lined Cap is a beanie designed to be worn by the 9 classes of TF2. The texture and concept were created by Aeon Bollig [https://www.artstation.com/void001] and their partner, I just created the model and promotional poster (which was later painted over by them). It's a fluffy beanie with little kitty paws over the ears, with big plastic eyes and large kitty ears.
