When Dave Wagner introduced his Alien cams to climbing, the art of technical placements changed. Alien cams are the best thin crack protection. The Alien hybrid units excel in pin scars and technical placements. Dave's design has been and will be copied in the future but so far this original concept stands alone. With a strong single stem design and high quality webbing to connect to, the Alien acts as a very solid piece of protection. Solid wire connecting the pull trigger to the cams is very solid and strong for great numbers of placements and a long cam life. The CE Certification for these cams has been well earned with how well these cams stand out among other spring loaded camming devices.
