(1) Fairydown Everest, older model, very warm bag suitable for use above the snow line, will include compression sack, $300
(2) Torre model (now defunct outdoor store in Brisbane), snug and warm, suits winter use below snow line, or above snow line if you are a warm sleeper, one small repair, $250.
I also have some mountaineering boots and crampons for sale if there is any interest, they have only been used once.
