Made a 14-6 karo quilt for a friend as a christmas present.
It is made with a lot of room, 64" top down to 42". He is also 6'3" and 210.
I even needed to put a foot box in it instead of doing a draw cord that I wanted to do.
Material is M90 and 10 ounces of down.
The groundcloth is just sil nylon.
It is designed to get down to 30 degrees.
Just sewed the foot up about 8" then there are 5 snaps to keep the quilt together making it more "bag like", what he wanted.
I also made a black waterproof groundcloth. There are also 5 snaps on each side of the groundcloth to open the bag up even more.
Another 10" in the head tapering to an extra 6 inches at the foot area, (you can see this in the pic with the measuring tape).
The quilt is intended for fastpacking and unsupported record attempts.
The stuff sack doubles as a pillow and is attached to the groundcloth, (you can kind of see in one picture).
With the quilt snapped to the groundcloth, you can just put a closed cell pad down, pull out the bag, craw in and go to sleep.
I wish I would have done a 14-9 on the karo as you can shift the down way to easily.
The 4" of loft is measuring both to and bottom.
Weight is 17 ounces for the quilt and 6.5 for the groundcloth with stuffsack.
