I just got my two new sleeping pads from gossamer gear (shipped an hour after the order was placed on sunday!) and I'm now swimming in sleeping pads and wondering how I should reconfigure my sleeping system. I'd be pairing any of the following pads with a Nunatak Arc Ghost and a nice warm bivy, and I live in Texas so the coldest I'll see unless I do some travelin' is about 30F, though more commonly warmer than that.
I now have:
A cut down REI blue foam pad that's 12" wide and long enough to get my thighs for belly-sleepin' - this one's good for bike camping since it fits in the pannier (style points!)
A thermarest prolite 4 which probably will only be used for sleepovers at home (sleepover style points++)
Gossamer gear nightlight (torso size)- I'm guessing this is the warmest foam one I have, but it probably won't do for sleeping on my belly since my thighs will hang off. I'm small enough that I don't run into Ryan's "just three more inches" problem- obviously it was made for me! It's also the biggest when packed and therefore might detract from the all-important style points.
Gossamer gear thinlight 1/8"- here's the real question- what temperature range can I expect to be comfortable in with just this pad? I can also double it over and have a thicker torso pad. I also expect that it's thin and flexible enough to work well inside my sleeping quilt. I'm fascinated with this little pad.
How shall I build my new sleep system from this? I'm really curious about how insulating the thinlight is and am looking for input (since I won't see nights below 60F for a long time yet).
