Here's what other sites are saying:
A lightweight sling for alpine, ice, trad and multi-pitch climbs, the Mammut Alpine Trad Sling is quick to deploy one-handed and can be used for extending protection as well as anchoring.
Instead of a normal climbing sling, the Mammut Alpine Trad Sling is a single strand that reduces weight and space to your climbing kit. You can wear it around your chest like a normal sling, with the included carabiner clipped to the stitched loops at both ends, and you can still extend pieces and make anchors just as easily as normal slings. The only difference is a reduced weight and a minimalist feel.
