I concur with the rest...
Since my Big Agnes Sleeping Bag failed as far as the rating went to keep me warm in a tent...I use it in the hammock as a bottom quilt. Sometimes with the BA air core pad inside, usually not and a quilt on top now. It is by far much easier to just lay down on top of all the stuff then try to climb inside and keep it all smooth under you.
Costco has a nice quilt 550 to 600 fill in beautiful colors for $24.99 I think it was...got two of them. Now to see if they will not become all moldy while I use them in the hammock, due to where I live.
