I've got a hike planned on Saturday. Going to spend the night near the trailhead. I'll be bringing along my Matcat Deluxe as well as my new Speer Winter tarp. Plan to do some setup experimentation. Maybe bring a few different pads as well. With the underquilt, I haven't tried putting anything in the pad layer. Need to optimize the setup in anticipation of temps in teens in a couple more months.
