I've gone through a few climbing packs in the last decade. Before this one, I had been using the CAMP Rox+, and was pretty sad when they discontinued it. That pack lasted me about seven years before I really ruined it, and the Trango Crag Pack seemed like a good replacement.
Definitely not disappointed. A little smaller than what I had before, but the ability to stash shoes and a water bottle on the extra pocket on the outside helps create more space, and the top pocket is actually quite large, and can carry all food items/etc. No matter how it gets loaded, it seems to be able to stand straight up without tipping, which is pretty cool. My only two detractions are that it doesn't fully unzip down the middle like a traditional crag duffel, and I end up only pulling gear out from the top. In addition, there is a rope tarp built into one of the side pockets, but it's too small of a tarp for most ropes and is sewn into the pocket - I ended up just cutting it out.
However, for $100, I don't think there is a better pack on the market, and for sport/trad cragging, I really don't need more space.
Currently, it's holding - 80 meter rope, 25 draws, 10 cams, two pairs of shoes, light harness, headlamp, sunglasses, chalk bag and a plastic bag full of chalk, a couple rolls of tape, a very large nalgene, and space in the top for lunch.
Material is really durable feeling and has help up to heavy rain.
