For wool sock fans, the Wooleator is a must-own sock. The Wooleator is a thin, low-bulk sock equally comfortable for cycling or casual wear, designed to keep feet warm and dry in winter, but thin enough to keep feet cool and dry in summer. This sock is available as either USA Merino wool or a blend of Merino and Repreve®, a recycled performance polyester locally manufactured from recycled plastic bottles, reducing landfill waste. This lighter weight wool blend is ideal for 4-season use, and is moisture resistant and naturally antibacterial. Similar to the Aireator but in a wool blend; thinner than a Woolie Boolie.
