The Santini UCI Socks offer lightweight feel for ultimate summer breathability. Crafted with Q-Skin fiber, they're designed to fight odor when you get your sweat on, and knitted into a fabric that's akin to mesh, with holes to let fresh air in while the fibers wick away your sweat. The sock sits at the fan-favorite crew length for just the right amount of coverage, and the back of the calf features a small detail with the classic rainbow design to separate these from your basic white or black crew socks.
