UYN Aero Winter sock exploits the extraordinary thermoregulating properties of Merino wool to ensure maximum comfort during winter rides. To increase moisture wicking capacity, we have introduced the high-tech Texlyte Nano yarn in the strategic areas of the heel, toe and insole. The Cool Air Flow system, integrated into the inner surface, allows air to circulate around the foot creating an insulating layer. The Aero Winter sock features a three-dimensional leg structure that reduces impact with air and promotes aerodynamics. Comfort and performance find their perfect synthesis, even in the winter season.
