I have tried various options for keeping warm in the spring without much luck so I am considering an underquilt. I have just started reviewing the threads here. Lots of information. So far I am aware of JackRBetter, LeighLo, and KAQ underquilts.

I am trying to keep my backside warm in the 20's - 40's temp range. I have a Hennessy Explorer Deluxe hammock, modified with a zipper top entry.

Please give me some advice as to the best option for warmth, fit with my hammock, and small stuffed size. Thanks.
