Some hikers and mountaineers think of a crampon bag as nothing more than an extra safety precaution, but the most inventive backcountry enthusiasts use it to store additional climbing gear like slings, ice screws and climbing skins. Petzl's Fakir Crampon Bag has an internal strap that secures your crampons to keep them from rolling around or tangling with other climbing gear. The semi-rigid rectangular bag features drainage and ventilation holes to help eliminate snowmelt. Clip it into your backpack and see how many ways you can use it.
