La Sportiva Olympus Mons Cube
The CS3 lace is made from 49 strands of stainless steel permeated and wrapped in nylon to provide maximum strength.
Designed to work with you. M3 uses a 1:1 gear ratio and a larger dial to increase dexterity and grip for gloved hands. Quick lace take-up and powerful closure allows for micro-adjustment in harshest weather and extreme environments.
