An exceptional, lightweight liner that&';s been proven on the longest trails - use it as your sock system&';s baselayer, or on its own if you want to ride light. COOLMAXA(R) and nylon fibers are combined for exceptional moisture management, breathability, durability and softness. The patented five-toe design minimizes skin-on-skin friction that leads to blisters and lets your foot work naturally for better alignment and feel underfoot. Designed as a liner, this ultrathin crew also works well on its own for warm weather hikes and runs.
