In 3 days, I am leaving for a 7 day AT trek with friends. Our first night out, we may have temps near 20°. All of us are prepared for that range, except for one of the guys who instead prepared for upper 30s. I (as the guilty, responsible party) am trying to assist him into a situation where he will not freeze his b**t off. His current setup is a pad (no wings/SPE) and a 40° GoLite TQ.
I have a Jarbridge River 1 Season quilt, which I have used comfortably down to 42° (with a 3S Burrow on top). I have used the JB River at 32° with a pad light Gossomer gear pad in the hammock. I also have a 35° Burrow I can loan him. If he is in a thermal wear, and we add an insulated hot water Nalgene, (he claims to be tolerant of the cold), any speculation of whether this setup will get him down to the low 20s?
It appears only the first night will be that cold, the next should be at least 4-6° warmer. And if he totes the extra 2 lbs of the abovementined gear, we have a place to drop it after the 3rd day, so even the extra weight is negligible. It is too late to purchase new gear, so any suggestions from the hangers here?
For the record, the rest of us here have 10-20° Incubators and 15-20° top quilts or sleeping bags, so we are prepared....
