Review: Black Diamond Siren Harness

By a curious coincidence, the weekend I tested this harness, I led my hardest route, which was five grades (truly, five) harder than my previous toughest lead. We are still investigating this phenomenon, and in the meantime I am eluding the editors’ attempts to confiscate the harness – their hopes being to enhance their own rock powers with what, it turns out, may be one of the best sport-climbing harnesses out there.
