I am considering buying an underquilt. I get cold easy so I want a full length underquilt. Right now I use a BA inflatable pad with the insulation and it works well for me. However, I do periodically slip off and as you know, you don't get far off your insulation in cold weather without waking up real quick. I just haven't had as much comfort from synthetics as down in may sleeping gear so I am looking for a down quilt. I love my blackbird and would like to make sure the quilt is compatible. This is my first underquilt so any suggestions are welcome. BTW, I have read this forum tirelessly and sometimes feel more confused, but better educated!!! Thanks for all the good info.
PS Also curious about weight and volume of packing for those that carry a hammock, tarp, topquilt and underquilt. Seems like that would fill my pack pretty quick.
