I bought a ULA Ohm last year. I love the pack. But my son and I have switched to hammocks. He is 5, so he usually only carries his clothes, rain gear, water, and snacks. So now I need to carry 2 hammocks, 2 underquilts, 2 top quilts, plus my gear. Base weight is around 16lbs, just a lot of bulk. The 4 quilts and 2 hammocks pretty much take up the main body of my pack, leaving only the collar and outside pockets for our food and my gear. I don't have the income for another pack really, so I think I would need to trade my Ohm 2.0 for a bigger pack. Maybe the catalyst or mariposa? Most of my trips are with him. I only do 1-2 weekends a year solo. I'm guessing it will be at least 5-6 years before he is carrying a lot of his own gear. Just looking for advice.
