I do alot of long rappels and ascents, particularly in the deep sotanos (pit caves) in Mexico. how comfy is this harness for hanging out on rope for hours at a time just goofing off?? I use an SMC rappel rack for drops and a rope walker for ascents.

I made a descent to "El Sotano de las Golondrinas" in SLP, MX; A pit with over 400m in depth. I would not go down in this harness, instead, get a petzl harness that is made for caving, there are plenty out there. The main difference is the center of gravity, in caving harnesses it's a little lower than in climbing harnesses, which makes you stay in a sitting position when you're hanging freely from the rope and stay much more comfortable during long descents.

It is a standard climbing harness, so it will be okay for hanging around in. Look at the BD big gun or Petzl canyon harness. These both have bigger waist belts and leg loops which will distribute your weight better, causing less specific site weight spots.For really long rappels or just sitting in for a long time.I would not get this. I would get a harness with bigger/wider waist and leg loops.
