Camp USA made the Nano 22 Express KS Dyneema Quickdraw lighter than ultralight for faraway multi-pitch climbs. The Nano 22 carabiners boast Camp USA's lightest construction yet, and their small size fits into sunken stoppers, tight cracks, and small-chained anchors with ease. Dyneema gives the dogbone a surprising strength-to-weight ratio, and Camp USA added a Karstop Evo carabiner retainer to stabilize the bottom carabiner while you clip your rope.
