Part of our Throwback Collection, the Aireator 3" quarter cuff sock Survival of the Fittest was one of our original designs, featuring a blue double cuff with a pattern of cartoon sperm and the words, "Survival of the Fittest" on the foot.

The thin profile Aireator cycling sock features an open mesh weave over the foot top, making these lightweight socks ideal for all forms of cycling and everyday adventure. Breathable, moisture-wicking, and durable.
