Black Diamond Siren Review

We have a few mixed feelings about this harness. While it is light and mobile, and great for steep sport climbing, it is not very comfortable to hang in, and truth be told, sport climbers spend a lot of time in their harnesses either working a route or belaying someone who is. If we could be sure that you'd never have to hang in this harness for more than a minute, we'd recommend the Siren in a heartbeat, but the reality is a little different, and we think a harness like the Camp Supernova with a little more padding and a lot more comfort is probably a better bet.
