This is our review of the Petzl Ascension with a 2016 update. It has since been archived. For more options, check out our round-up review of ascenders available on the market today.
This Ascension Ascender from Petzl is lightweight, slides up the rope easily, and works on icy ropes. This is a redesign of the popular blue and yellow ascender Petzl has sold for years. Those ascenders were our favorites and the new versions are very similar to the old ones.
Although we are not sure the new design is a big improvement over the old, the Petzl Ascension remains our top pick for ascenders and is an essential piece of big wall climbing gear. It slides up the rope easily, is easy to get on and off the rope and is light.
