Detailed description

JLF Pro’s extra warm K2 sock provides effective protection against the risks posed by cold. Its composition, based on Merino wool and Thermolite® polyester fibres, makes the sock very warm and provides perfect insulation from cold and heat. It also has a curly insole reinforcement on the tongue, shin, calf and sides, extending to the toe. In addition, this high sock has a ventilated area on the top of the foot to provide breathability and to remove perspiration more efficiently. It also has polyamide Cordura material in the heel and toe, making the sock stronger and more resistant to abrasion.
This cold weather sock is also compatible with, and recommended to fit, antistatic clothing and conductive (ESD) or antistatic footwear. It does not alter the electrical properties of the shoe. It is recommended for protection against cold from -5° to -15°.
