It's nice to learn by doingOk, I took it out for a test spin...
The layered insulation worker really well, more insulation above my body core, less out at the edges.
The Fabric I used was two to three times heaver than the fancy sleeping bag materials so it's a little stiff. It doesn't drape as easily and lie on the ground around the edges like my down bag does. Because of this it's more drafty. I might add some elastic straps like in the Nunatak Quilts mentioned above. Eventually, when I make the fancy version, I'll use the lighter material.
Final version should be about 50% lighter and warmer too, it'll also cost five times as much.
Took it up to the "lunch counter" on Mt. Adams last night and had a blast.
Can you add some softer material to the edges of your quilt to make it drape more close to your body?
Do you need a reservation to set up camp in the Lunch Counter? The place looks like it shelters from the wind...........does it?
Thanks for doing the video and sharing. Does the snow ever completely melt up there?
