Ultra-lightweight and extremely compressible. With a progressive design and intuitive climbing features, Mammut's climbing backpack is light and packs up small. It keeps all your crag gear securely in place in a large main compartment and roll top compression. Anatomically shaped, padded shoulder straps keep happily hauling. The Neon Light 12 packs' short and slim body and gear loops make it ideal for climbing rock or ice.
