A large pack, pretty comfortable if adjusted properly to the wearer. The stays need to be formed to fit your back.
Only thing I didn't like was the woodland camo pattern and the one single pocket on one side and two pockets on the opposite. It made it hard to balance the load. I used one in SF for sometime and it was way better than the standard ALICE thing. That was a killer if you are over a certain height.
I would say the CPF90 is a good pack if you don't mind the camo material. I actually have an early prototype in OD with 4 side pockets. Vector, a subsidary of Lowe Alpine first designed the pack and I used to get samples from time to time. I was able to keep the OD cordura one, still use it regularly. Hope that helps some.
