a couple weeks ago, I went on a quick overnighter with my son and his boyscout troop- I use a sportsmans guide hammock with military poncho liner as an underquilt(inverting the hammock and putting the liner into the bug netting) and a 10 degree mummy bag as an over quilt. A pair of polypro unders and thats it- got down to between 25 and 28 degrees that night and I was comfortable in the set up- is this normal, and how much colder will this set up allow me to go- any info would be appreciated- still relatively new to this hammocking thing- and have been making it up as i go along- thanks to all those who post the valuable info here!!
