Wooleator Pro 6" Faze comes in two ombre color variations: natural to gravel grey, and light grey lead to blue petrol. The NEW Wooleator Pro features a flat toe seam and additional lycra throughout the sock, providing a closer fit. Like the original Wooleator, the Pro is a thin, low-bulk sock in USA Merino wool. The Wooleator Wool Blend versions also include Repreve performance fiber, moisture-resistant and naturally antibacterial. The Wooleator Pro is equally comfortable for 4-season cycling or casual wear.
