this will be my first winter in the hammock.

wanting the most efficient system from the start, i started with landau ccf, and
then bought 3 - season uq - yeti and crowsnest.

planning the mt. rogers hang, my question is:

is it general practice to use ccf in conjuction with the uq?

it seems macs ix would be a good barrier between the uq and the hammock in extreme temps: 5 and below
