Very nice sleeping bag, material feels great. Zippers work well. It is almost exactly what I was looking for. Fill is should be good for above 40. Good design! Love the straps and holder for air pad. Very lightweight as well.
This bag is unbelievably cozy. The 700FP down lofts up immediately and creates a perfect pocket of warmth. The drawstring hood lets you create a snug fit around your face. Slept like a baby in near-freezing conditions.
I was skeptical it would pack down so small, but it truly fits into its compression sack with room to spare. For a bag rated this low, its packed size is incredible. Frees up so much space in my pack for other gear.
Used it from 45°F down to 15°F with appropriate layers. Performed flawlessly. The quality of the zippers, fabric, and stitching is premium. This feels like a bag that will last for many, many seasons.
The 3-in-1 concept is executed perfectly. The zippers align easily, the pieces stay connected securely, and each component feels high-quality on its own. A truly well-thought-out product.
