This is the Sewn through 50f and Mummy Shape version of the Newt Hybrid Quilt. It’s narrower in the torso than the fetal position systems. It’s meant to bend with your legs rather than allow room to curl up inside.
The Newt is a hybrid system between my false bottom design and a traditional quilt. It has a false bottom up to about the hip area to keep the edges under control and the drafts out. 12″ of the total torso circumference is the false bottom. The top third of the system is open like a quilt so the user can ventilate or cinch down. This combination is an attempt at joining the benefits of each system into one. The draft free and warmth of the false bottom design and the easy ventilation and open feeling of traditional quilts. It’s also meant to improve upon the drawbacks of each. The lack of ventilation options of the false bottom for warm sleepers and the drafty nature of quilts for colder sleepers.
Another benefit to this design is that the top width can be trimmed down to shave weight if desired. While the False Bottom Sleeping Bags require a top circumference that is large enough for the shoulders to fit through and often 5″ more than the shoulders circumference for comfort, the Hybrid Newt can be sized right at the shoulder circumference or 5″ under.
It has horizontal, sewn through chambers with 950 fill power down. 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.
