Sleeping bag as underquilt??

**Ewker** · 10-24-2006, 18:39

I have a -5° sleeping bag with a full length zipper. Could you use that as an underquilt?

Is it rectangular? how long? how wide?

A rectangle with some sewing should work, I ran across one online somewhere but can't remember where. I mummy bag might work with some more sewing. A -5 bag may be heavier than other options, but then it could get you colder.

Only one way to find out.

it is a mummy bag. When you open it up the widest part is approx 60" wide. The zipper stops about 18" from the bottom of the bag. The bag is down and weighs 3 lbs

Unless your pretty short a mummy bag won't work very well as an underquilt. Unless you want to cut it up some, but I couldn't do that if it were mine. would make a pretty good top quilt though.

I have no clue as to what the fill is. All it says is that it has 2 lbs of goose down. Anyone remember the Backside Sleeping bags? That is the brand. I have had it down to 0° and had to unzip the bag some.

If you are open to sewing the bag to lay flat and as open as possible (read no longer use it as a bag) I don't see why you could not use it. You would really have to adjust the foot end so that the insulation is right were you lay.

Maybe one of the sewing experts would be able to help more.

I didn't even think of the length issue. Maybe you could pick up a cheap bag somewhere first and try it out on that first.

I had prefer not to cut it up. I was just hoping that it might work as is. I don't need that warm of a bag most of the time but it is nice to have just in case

It is 84" long

I have a 20 deg mummy bag I have used in a hennessy by placing 1/8 in. thick closed cell foam pad in the hammock with me. have been good down to 30 deg. with this setup and the pad only weighs 3.5 oz. I think it was auto headliner foam. Its pretty soft for closed cell foam.
