What do people think of this sleeping bag? Denali Lite 50

G'day,
Still haven't got all my s... stuff together. Anyway, I'm looking at the sleeping bag that I thought would be fine. 1.7kg, and bulky as. Looking at doing a two day hike in the Alpine National Park. Would this bag do the job? Would it do it well enough to keep me warm at night? Anyone else got this bag?
