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. These Hybrid Aliens are great for protecting flared cracks such as pin scars. These cams have CE Certification that holds for even the uneven placements in rock. Fixe Has another great piece for thin crack protection in these cams. The hybrid cam has the nice, smooth action expected from other Alien pieces.
