Pearl Izumi Merino Thermal Sock

We get it. Most Merino socks start great and go threadbare before the season is out. Ours benefit from a blend with recycled polyester that makes these socks as durable as a steel frame. They are also fluffy-slipper-warm thanks to being twice as thick as our other socks. The toe features a flat seam for comfort in snug cycling shoes.
