I went to Costco today and found the new replacements for the Double Black Diamond Down Throws. It's an Eddie Bauer branded 60"x70" blanket. It's a little less than 200g heavier than the DBD (w/o bags) and won't fit into the smaller stuff sack of the DBD. Oh, and it's on sale for only $12.99.

I just got it washed and dried, so I can't yet attest to the warmth and I can't find any information on the R-value. It says it is "Primaloft Black Series" insulation on the Costco site, but I can't find what that equate to anywhere. I found an older reference that compared it to a 550-fill Power Down.

Anyone tried one of these out for a DIY or just top insulation yet? How's it do and what temp did you take it down to? It's the first I've seen of them in the store.
