Sitka team decided to include them as a necessity. At the same time, they decided to upgrade them and evolve towards a new bra clip fastening system that attaches to the newly reinforced webbing loops on the Ascent and Mountain Pants. A new cam lock makes for easy and secure adjustments in length. Urethane elastic with rubber gripper will outlast every other suspender in your closet. An optional addition to the Mountain, Ascent, Timberline, ESW, Stratus and 90% pants. One size fits all
