I am considering switching to hammock hanging from a tarptent Rainbow after discovering the HH Hyperlite. My main concern is keeping warm which I know is a concern to many. I don't want to spend all of the money and weight with having an underquilt/overquilt. The HH Supershelter looks like a nice lightweight alternative that could be extended with garlington insulators, etc. However, it just looks way to expensive for what it is. Is there another site that sells simple silnylon undercovers to fit Hennessy Hammocks?

I would make one myself if I had a sewing machine and the skills to do so. Perhaps I'll start making my own gear once I get back from my AT thru hike in September.
