Darn Tough Thermolite RFL Over-the-Calf Ultralight Sock

RFL is the lightest sock Darn Tough Vermont makes for skiers and riders. Minimalist construction still provides plenty of warmth and a smooth, streamlined fit.

This sock just disappears when you put it on, allowing you to feel the terrain underfoot. Thermolite fabric and insulation provides warmth and comfort without weight.
