The Darn Tough Men's Bike Breakaway Micro Crew Ultra Light sock is a sock for sock purists. The streamlined design of the 1790 sock hugs your foot with no bulk and no seams to get in the way of your ride. It's made of fine-gauge merino wool and designed for a breathable, itch-free fit. And the 1790 sock wicks moisture, dries fast, and naturally repels bacteria and odor. These are tough socks, and the company backs up its word with an unconditional lifetime guarantee.
