Petzl Hirundos Climbing Harness Review

The DoubleBack buckle system is a single, pre-threaded buckle on the waist belt (or, in the case of the Adjama, on the leg loops, too). Many companies are now turning to pre-threaded buckle closures that you can adjust with a single pull. I’ve found that Petzl’s DoubleBack system works the best—a little groove for your thumb allows you to easily catch and pull the buckle to take the harness off. When you put the harness on, the action of pulling the webbing is smooth.
