I would like to winter camp in a 4-season tent but am interested in alternatives to mummy sleeping bags. I want to avoid that shape.
What alternative sleep systems do people use that are appropriate for winter camping?
- Self-inflating sleeping pad with foam core, R value = 4
- Daytime temperatures below 32F/0C
- Nighttime temperatures bottoming out around -15F/-26C
- Precipitation, sometimes heavy, almost always snow
- Moderate winds
