X-Socks Trekking Desert Storm (2 Pairs) (Men's) - Light Grey/Grey

This trekking sock features the special sock-in-a-sock system. The integrated second sock reduces friction that can cause injuries during long treks and in conditions when the feet are subjected to extreme strain, e.g. when mountain climbing. Many mountain climbers - and soldiers - choose this model for its unbeatable combination of durability and comfort.
