Wren camping quilt
The Wren is a traditional camping quilt. The insulation on the underside of a sleep system is compressed and has very limited effectiveness. Quilts came about to address this issue by just getting rid of it to save weight. The Wren has horizontal baffles, a full differential cut so you can't compress the down fill, and has a drawstring footbox that allows you to vent. It also is fully wearable and can be used as a jacket or for warmth around camp. I use two top snaps and one mid strap to keep it in place while you sleep. The strap can be used around the sleeper, around the pad, or unclipped. It is important with any sleep system that it is paired with a sleeping pad rated to similar temperatures. It is especially important with quilts and false bottom bags and it should be noted that pads that utilize empty spaces are generally not suitable for these types of sleep systems.
This should be used with a Waterbear hood or can be used with other types of head insulation.
This can be paired with a Merganser overbag that clips together with it
All sleep systems are 80% overstuffed over the baffle height for dense chambers that hold down in place.
