The La Sportiva Mainliner Pant is a climbing pant made from heavyweight organic cotton blend twill that stands up to abrasion from rock day after day. Doubled fabric covers the knees, where scrapes and scuffs land first, and articulation at the joint keeps high steps unrestricted. Stretch in the blend moves with every reach, so the same pair carries over from the crag to the street. What Our Gearhead® Experts Are Saying:“The belt loops lie flat against the waistband, so the hip belt of my harness cinches down without a ridge pressing into my hips. That keeps these climbing pants comfortable through a full day of sport climbing, belaying, and hanging at the anchors.”
