Sleeping bags:
Then new single mummy style Polar sleeping bags with fleece inners were used by some members of K049. We found the bags were unsuitable in temperatures below –15°C when using the old mattresses that included the closed cell foam insert. On Mt Erebus the performance of the bags was satisfactory with the addition of a separate old style polar outer bag and a thin foil mattress on the standard mattress.
page 16- A warmer and larger bag than the new Polar bag is required for the early season, high altitude locations and larger people.
- Many of the old mattresses should be replaced. A new mattress or combination should include an insulating/waterproof closed cell layer, a comfort layer 2" thick and a heat reflective layer.
