I've only had it about 6 months. I have plenty of room but it just depends on how much you take. I have the 2400 which is the 40 lt. It holds my summer gear just fine, except I have to strap the bear canister on top. I'm guessing that at least for me the 4400 would be too big, but I try to carry minimal stuff.
