I'm taking mine out tomorrow for and overnighter to yellow river state forest. Supposed to get down to 42 and foggy. It will help me decide on what my warmer quilt will be. 3 season or winter burrow. I'm thinking if I'm comfy at 42, I'll just skip right to the winter burrow as I already have the Winter incubator. I used a 15 degree synth bag and a pad year round before I went to quilts so I'm kinda used to overkill.
