Found: DeFeet Thermeator Winter Cycling Socks
Just in time for the coldest parts of winter, the new DeFeet Thermeator offers an insulating, quick drying sock that’s about 30% lighter than a comparably knit wool sock. They say it’s also a bit thinner for less bulk inside your shoes.
The yarn is two thirds THERMOLITE polyester, a hollow core fiber designed to trap heat. The rest is Nylon and 2% Lycra for durability and stretch. Cuff height is 6″, retail is $14.99 a pair and they come with blue, pink, gray or red color accents.
