Mammut Crampon Pocket
Here's what other sites are saying:
The Crampon Pocket from Mammut can be attached to the outside of any of their alpine backpacks to make sure the crampons do not damage other equipment.
You get back to the car, go to open your pack, and are confronted by a poof of feathers as soon as you unzip it. Down jackets are sweet, as are crampons. Y'know what's not sweet' When they hang out together in close proximity. Throw your 'pons in the Mammut Crampon Pocket attached to the outside of your pack, and avoid being the guy at the bottom of the trail with a face full of feathers.
The Mammut Crampon Pocket can easily be attached to the outside of a pack to ensure that your spikes don't start eating the rest of your gear. Made from ballistic nylon, this holster will hold up to sharp edges and rough terrain.
