Lots of Storage!!!
This is an amazing pack. Just to give you an idea of the interior size of this pack... I can pack up to a 400 foot 11mm static rope inside with all my biners and harness for a fun day of rappelling. My only gripe is the hydration pocket inside is useless. I can't even fit my hand inside and there are no side pockets for water bottles. The pack rides very well on my back and the waist straps contour to my waist very nicely. I think you could easily fit a 70 meter dynamic rope and a few days rations inside for a few nights on the crags.
