I bought this bag for my first two day climb: the South Face of Washington Column in Yosemite. We hauled to dinner ledge, fixed a few more pitches, and spent the night on the ledge. The bag held up great. We hauled on low angle terrain and there is no sign of damage. I also really appreciate the river-bag style closure on the Metolius Half Dome. Not only is it water proof, it's critter proof. Another team on the ledge had a haul bag with a simple draw string closure, and their food was ransacked by squirrels. Our bag was untouched. As for the size, we definitely could have done this wall with a smaller bag, but the Half Dome is big enough that it should give us space for larger objectives in the future.
