"Great for a climbing pack (i.e. climbing with this on your back)"
Just got this a few weeks back, I have used it a few times and I am very happy with it. It is fairly small, but sits tight on your back when climbing. It has a chest strap and a waist strap, but sits up off your harness out of the way. It is perfect for bringing water, lunch, rain jacket camera and assorted gear. I cant believe that I waited this long to get a pack like this. Absolutely perfect for multi-pitchh trad climbing. However, I would recommend not to venture up too many off-wideths with it because it is thin nylon. Anyway, it has a few small scratches but nothing to big after a few trips up the crag. Also, did I mention how light it is! You barely feel it on your back!
