I haven't got or made a hammock yet but am definitely intrigued. I have a comment and a question.
First, the comment: there is no way I can see that a hammock would be lighter than my current kit. I currently use a silnil tarp with a little bug net I rig over my face, a piece of Tyvek, a Z rest, and a Marmott Hydrogen in size long. Total weight is just under 3.5 pounds for shelter, pad, and bag. I have been looking at Ed Speers hammocks because I like the idea of being able to leave the bug net behind, sit in the hammock easily as a chair, etc. Even if I can solve the warmth issue without going to a Peapod, I'm over 4 pounds for a hammock, fly, pad, and bag. If its cold, it gets more complicated .... and heavier. How do so many people claim they are reducing weight by going to a hammock?
Now for the question: has anyone tried a Big Agnes style bag in a hammock, or somehow attached their pad to the bottom of the bag so it can't slip out from under the bag? Does that work? Could you attach a couple of straps at top, middle, and bottom of the sleeping bag (on the underside, of course) to hold the pad in place?
I figure I'm going to get a hammock soon just to see what all the fuss is about, and am very open to advice.
Thanks in advance!
