The black CC bag was reviewed by someone on CPF. Conclusion was that it's an imitation Snugpack, not the real thing, but probably an ok value at $40.

Also, sleeping bag temperature ratings even from good brands are marketing fantasy. Don't believe them for one second. Get one rated for several levels colder than the coldest temperature you'll actually use it in.

I have a TNF Chrysalis that I use as a summer bag and it's great for that. But it's rated for 20 degrees F, which is ridiculous. It's chilly at 60 F.
