I would like to make or have made an underquilt for "hinge season" rated to about 45-50 F. I envision a peapod that could be equipped with a zipper to make it a quilt as well...

Here's my question--How light can I go?? I originally wanted to go with just a sheet of silnylon with DWR and hope that it provided a pocket of warm air between the hammock and the outside air. I am sort-of doubtful about this solution, but maybe someone has some experience here...

If that was not enough, I am probably going to go with climashield for insulation, and try to make it as light as possible. Is this the proper insulation??

The whole point of this is to try to eliminate the CCF pad...I don't like the weight or compressiblitly for warmth that these pads offer...if I could make a peapod that was uberlite...say 10-13 oz...I would be able to have the hammock feeling into the low 50's I would think...and sans pad....

All of your input is greatly welcomed and I am thankful you all are here...Good day!
