I use this pack for everything from cragging, where it holds a full rack, rope, helmet, shoes, and lunch all inside the pack - to alpine overnighters where you then add a sleeping bag, pad, half a tent, stove, and rain gear by extending the spindrift collar and top lid. It carries 30lbs nicely. I've had mine for a little over 2 years now and it's holding up very well. No broken plastic after two trips to GTNP, several 14ers, weekend sport/trad climbing, etc... My only issue is with all the extra long webbing, it can get to lookin' like a nylon dread-head hangin' from me back mon. But it's all those extra webs that allow the pack to convert from a mountain load hauler down to a sleek summit pack.
