The Mammut Helmet Holder Pro is a protective storage and carry accessory for your helmet. Unlike a standard helmet holder the Helmet Holder Pro has a zipper allowing the helmet to be fully enclosed giving it protection from scratches when on the back of your pack. This also means that it can be used to protect your helmet when not on the back of your pack. To attach it to your pack it has 4 hooks on elastic which are designed to work with ant attachment points on your pack. The fabric is flexible allowing it to fit around almost any helmet and there's a button fastening to compress it for transport when not in use.
