Instead of tearing up your backpack with your crampons or having your skins take up way more room than they should, stuff them into the Marmot Crampon/Skin Pocket. Made with durable fabric and a PVC-free tarpaulin bottom for added abrasion and waterproofness, this nifty little pocket has an internal mesh pocket and a drainage port. It also has a dual daisy bottom for securely lashing to your backpack and internal compression straps ensure your crampons stay in place.
