Modern head art in mosaic design. This docker cap from Stetson, a modern head art in a mosaic design, is made from a high-quality material mix containing cotton, wool, linen, and silk. A soft microfleece lining made of 100% cotton provides additional comfort. The fabric cap impresses with its snug fit, leaving the ears and the back of the head largely exposed. With its minimalist, round design featuring a patchwork pattern, the docker is perfect for those who like it simple yet striking.
