Got a set of North Face Fleece Salopettes. and a Montane Pertex/fleece jkt (Like a buffalo but better) for sleeping in. Throw an Ajungilak Eskimo -20 sleeping bag & a fleece bag liner, & then stick all that in a gortex bivvy bag in the back of the disco & I don't think the cold is going to be much of a problem.
