I tried the search function, but got too many hits…
I found a Kelty 20* down bag at my local Target, seems similar to the Cosmic 20* but is called Light Trekker 20 degree. Anyway, the box lists the fill as 20 oz. of min 75% 550 fill duck down. Comparing the specs to other bags, it seems a bit low on the fill volume. It's priced at $90 is this too good to be true? Any reason to think this will keep me warm on a cool 30-40* outing? My typical use will be staying at State/National parks, no back country camping.
Thanks!
