So I'm thinking I'm going to be hanging @ roughly 20-30 degrees F this weekend and not sure if my hammock setup is warm enough. I have a clark NX-250 with crows nest 3 season UQ with 3 extra ounces down stuff, a 0 degree mummy bag, fleece liner, and themal tops and bottoms, and will be trying the hot water bottle thing.and I'm a warm sleeper, I ask because last October I went with just my hammock and sleeping bag and had seroius CBS it was in the high 30's to 40's then. Now I have a UQ but have no time to pretest before the hike. So with this in mind what do ya'll think? Worst comes to worst campfire or hike out but I'm pretty sure all this is good enough.
