Just ordered a 20F (-7C) 3/4 Phoenix. I have been using the HH super shelter but wanted to try a UQ. The HHSS left me a little cold too often.
My question is whether 20F implies 'While you're wearing a down jacket and thermal underwear" or whether I should be able to put it below my BB 1.1 DL and be comfy with my down bag used as a TQ.
Any tips for first time UQ users? Common mistakes? Special prep/treatment? Storage? I'm excited yet nervous.
