Jerry – good comment on the solar value of a dark sleeping bag cover – that makes a huge difference in colder air temps.
Looks like a nice bag despite the light cover – competitively priced. Wonder why it's not sporting the DriDown. The EN rating is 30* for woman and 19* for men.
The comparison needs to be made to the Marmot Plasma 15 – very well designed hood, draft collar & footbox wrapped in a Pertex Quantum cover – one degree warmer on the EN rating – though cost wise you need to wait for the sale prices.
I've been watching for the Plasma 0* for about a year – I see they finally now have those available – I'd start waiting for the sale price but my 2006' 900 down Quantum cover Lithium is in perfect condition and weights the same even though I added 1.5oz of 900 to the draft tube – I also like the fuller cut for ventilating and ability to add layers without as much compression.
