I had the good fortune to hang for 4 nights in Skidaway state park near Savannah for a weekend of Geocaching and camping. I have yet to make an underquilt, and I knew I was going to need some sort of insulation. This is my first hand where temps were below 80 so I wasn't quite sure what I was in for. The first night I put the pad under my sleeping bag...that didn't work so great. The next night i placed the pad in a fleece bag that I had brought with me and slid it inside my bag. I sleep warm and comfy for the remaining three nights, on of which got down to around 34º. The fleece sleeping bag was way to big for the pad so there was a great deal of shifting around, but much better than under everything. So I got to thinking...I should make a pocket of fleece to put the pad in so that it fits the pad snugly, to help reduce the wiggle factor.
I found some fleece on sale at Joann's and got to sewing I do understand that it's not LW or UL for that matter, but most of my camping is car camping, and 2-3 day trips as that's all I have time for these days. I hope to get to test this out sometime soon and will report back on how it works. It was a simple project and thought I would share for others out there that haven't or are a bit leery of starting a UQ project.
