Smartwool Liner
The Smartwool liner can be paired with a thicker sock to provide extra insulation against very cold conditions or used on its own where it feels like second skin. It also adds insurance against blisters or chafing under heavy loads or on extra long days. The flat loop toe seam eliminates hard spots and a flat knit gives a close fit.
Fabrics: 64% Merino wool, 34% Nylon, 2% Elastic
