I'm fairly new to hammocking & backpacking. I have gathered that I don't have the experience or budget to purchase an underquilt. I am however, budgeting for a down bag and a pad. I have seen much about open/close celled foam but not much about air pads. It seems they are thicker, easily compressed, and can vary the pressure within to manage comfort. My question is, how well do air pads work in a hammock?
