Although it might look like it, Petzl's Anneau Polyester Sling isn't the same sling that old-timers used back in the day when climbing shoes didn't even exist. These bar-tacked slings have a more rugged feel, and at the same time, feel thinner for compact convenience on the climb. Each sling is excellent for racking gear, building anchors, or extending pieces. Petzl color-coded each length for easier identification.
