These S/M unisex patterned crew socks come about halfway up the calf. They are a soft and stretchy blend of 70% cotton, 28% polyester, and 2% spandex. S/M socks fit sizes 4-9 US Women & 5-8 US Men. We also have an M/L sizing available for separate purchase, including 9-13 US Women & 8-12 US Men. Yellow ankle, heel, and toes are attached to an overall green body. The duck characters wear a light blue eggshell on their heads—repetitive black speech bubbles with "WTF" in green font. One sock bottom has "DUCK" sentiment while the opposite sock has "HEAD" sentiment in black. Machine wash cold on a gentle cycle with like colors. Tumble dry low. Never bleach or iron. These humorous duck socks are great for giving to co-workers, duck lovers, farm lovers, or zoologist friends. Packaged in a plastic polybag and secured to a hangable thick cardboard sleeve that contains care instructions and sizing info.
