Icebreaker Women Mountaineer Mid Calf in the colour Monsoon. For making big attempts on big mountains, put your trust in the Women's Mountaineer mid calf sock. Fully and densely cushioned, the Mountaineer is engineered to fit great inside your boots, provide all day warmth and breathability, and give you a little extra cushioning.

A seamless toe box prevents bunching, especially important during a long descent, and reinforced toe and heel areas mean they'll be your trusted partner for many expeditions to come.
