This excels at wall routes where there is 90% free climbing with a couple aid pitches. For example, I would take this on the Regular Route on half dome because I want to travel light on the big approach and there are really only a few hundred feet of aid.go to full review
Overall, they are a specialty item only suitable for experienced wall climbers who climb walls fast (and even those climbers may not want them). The main competitors are the Yates Speed Stirrup, which is much heavier but more comfortable, and the Metolius Easy Aider, which is a little heavier and more bulky but also more comfortable and a hair cheaper. Overall, I lean toward the Petzl because the whole point of an aider like this is to be as light and streamlined as possible.go to full review
This is a durable and classic design. Chris Mac says he has never worn out a pair and has not seen any wear out. Because it doesn't have any extras, this aider is relatively light and less bulky than most other aiders when clipped to the side of your harness.go to full review
