Here's what they give for specs:

Down sleeping bag
comfortable down to 20 F
Fill: Grey goose down, fill power 600, 80/20
Fill weight: 23 ounces
Pack weight: 2 pounds, 14 ounces

The fill power and fill weight don't mean a lot to me. I have no experience to base it on.

But here's what I was wondering, while it may not be good down to 20, with those specs can one assume it might be good to 25, or 30, and if so, do you think it might be a good deal at that $89.99 price tag?

I think the "exponent" gear I've got from Coleman has been pretty good for the price I paid.
