A double zipped bag that is designed for storing ice screws and similar sharp objects in your rucksack.
At the end of a day's climbing, the whole bag and contents can be hung up to dry as it has a mesh panel to aid air circulation, and stiffened sides help it retain its shape.
It will hold at least a dozen ice screws.
Dimensions: 26cm x 13cm x 10cm.
Weight: ca 110g.
