I have a Pop Up 28 for 3 years now. Hell of a great little day pack. It's built like a tank and a very capable little hauler. MR rates it to haul 80#, but I've seen stories of guys packing 110# and more! I try to stay at 60# or less, but I'm 65y/o and would rather do an extra trip these days, than risk hurting myself.
