This version of our Lightweight CoolMax® Crew Sock has the same durable attributes, but is in a quarter length to provide additional comfort on hot workdays. The CoolMax® special performance fabric moves moisture from the skin to the sock's surface so it can evaporate quickly. The sock also features anti-odor properties; mesh-knit instep, arch and ankle panels for great ventilation and breathability; a cushioned foot for comfort; a 'no-feel' toe seam; and a spandex-reinforced arch for a secure fit.For over 115 years, Carhartt has manufactured premium workwear known for exceptional durability, comfort, quality of construction, and fit that you can feel in the fabrics and see in the performance.
