One tester, Chris Van Leuven, used this on a number of El Capitan ascents. While it is generally not recommended for big walls, CVL found the advantages of such a skinny harness: it is light, gives a big range of movement for free climbing and is comfortable to sleep in because of the soft gear loops. That said, Chris vows to take a more comfortable harness on future big wall routes, a harness with more padding such as the Petzl Sama.

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.
