Comfortable enough but...
I have the 2008 harness which looks about the same. It is a fine harness, it's definitely comfortable enough for normal climbing but I still wouldn't want to hang in it for a long time, though no harness really fits that bill. My biggest beef with it is that the gear loops are sleek and low profile which is fine except when you want to clip or unclip things to or from them, in which case it's less than convenient. It would also be nice if it had a full strength haul loop.
