Small enough to carry to the top on those shorter climbs where you might want to carry some extras like lunch, 1 inch webbing and anchor building supplies. Mostly, just a comfortable top loader that does everything it was designed for well. No daisy chain webbing down the back... no problem. Just string some cord between the tie ins and you can hang whatever you want. Two loops off the bottom... I use one for my hammer whose tether is girth hitched on my harness. Basic bolt kit and drill holder are inside the pack every climb... just in case! Still room for lunch, windbreaker, webbing, and a couple of beers to sit back and enjoy the view at the top. Great pack!
