At first sight the neon green dental floss hirundos looks like a harness used in the bedroom and not at the cliff. Even when you slip it on, you wonder if it will even hold a fall. Well it does, and it feels amazing at the same time. Being the sport weenie I am I've spent hours, yes hours in a hirundos dogging up a route and the only pain I noticed was that of my ego being smashed yet again. Petzl nailed it, the way the frame construction evenly distributes pressure while keeping you cool at the same time you'll have a hard time giving this harness up. I've had mine for over a year and it probably has over 1000 pitches on it and it still shows minor wear, I could easily get another 1000. Clip on a gri gri with a 3-d attache and a handful of petzl draws and you have the perfect fail safe setup.
