For thin ice, small gear, or places where protection is questionable at best, clip into the Mammut Dyneema Shock Absorber. This quick-draw-style runner features an exterior coating that holds a folded over runner. When fall force exceeds 2.5 kN, the tiny seams holding the runner together tear, lengthening the runner to full size and reducing fall factor by 30%. With a sketchy piece of gear or a screw in unstable ice, 30% could mean the difference between a whipper and a body bag.

great peice of gear

  • Familiarity: I've put it through the wringer

These shock absorbers are light weight, quality constructed and durable. I have about 30 climbs using these and had one partner fall on one, engaging it. These are both smaller and considerably lighter than screamers. If you don't mind spending the extra money and weight is an issue on your rack for long approaches or big climbs, I would highly recommend them. I use them exclusively.

Great piece of kit!

    Having used all the Yates versions and these I have ditched the Yates. These are lighter and easier to carry and use. Down side is they are expensive. But worth the extra coin imo. I use them on almost every screw placement where I would be hard pressed to actaully use the Yates becasue they are cumbersome.

    Great piece of kit!

    I'd rather have a shorty.

      These are fine, but I'd rather have a Yates Shorty Screamer instead. Although slightly less bulky than Screamers, the Mammut Shock Absorbers have a higher activation force. I'd rather subject the placement to as little force as possible if the placement, pin or screw is sketchy.

      Mammut Shock absorber

        This is a very specialized peice of gear and does not need to replace all your dogbones. At what it does, it is so great. I have 4 that I use on super sketchy gear when aiding and climbing ice. The Dyneema is rad, these used to be made by Yates with standard nylon and they were super bulky. These are great. You wont want to ever use them, and when you do you will likely be crapping in your pants, but you will be really gald you have them.

        "...these used to be made by Yates with standard nylon and they were super bulky."

        1) They still are and 2) insignificatly so. Stick with the Yates screamer and use the screamer "zipper" (same price as mammut) of your first piece (zipper one is activated by less force)

        What is the weight in grams?
