Pushing the evolution of ascenders

the Index allows trigger-finger access to help you manipulate the cam for easier operation low on a pitch or during hard- to-clean traverses. The dual-density grip and trigger increase comfort for long days on the wall, and a large clip-in hole lets locking carabiners rotate 360 degrees for easy rigging.
