50 L pack, used lightly for a season....used it for a couple cross country ski treks last winter when we had snow, been sitting in the closet since, while I use my shimoda and I am trying to get rid of things not in use
Great pack, just larger than I need now or in the forsee-able future.
I do have a selection of Internal Cube Unit sizes as well for a little extra. (small, med slope, med pro, large)
