Sleeping Bag to quilt

I am surprised that this thread had no response of any kind…

For starters, I have an old North Face sleeping bag that I was wondering what to do with, and obviously a conversion into something else would be easiest task. (albeit my first thought was tearing some seams, pulling out the insulation to use for a future project, waterproofing the hell out of it and making a bivy? Any thoughts on that would be appreciated)

Second, I think your pics were terrible :-) I saw the thread title and thought this could be fun… I just happen to be a visual learner so the more details in the pics, the better it would turn out for me.

Anyways, kudos for the project and thanks for the inspiration.

Yeah the pics are terrible, my camera is great for outdoor sunny photos. It just won't take good indoor photos no matter how bright I make it.

I am not sure I would use a sleeping bag to make a bivy. There would be alot more effort in that process than this took, also there would be thousands of needle holes from where the baffles used to be sewn to the shell material. I think your best bet would be starting with fresh materials for a bivy and converting the bag to a quilt. Let me know if you have any questions about the conversion and I can take the quilt outside on a sunny day this weekend and get better photos.

Yeah, the bivy idea probably isn't the best, it was just the first thing that popped into my head since its already the shape I want :-) I just found this website 3 or 4 days ago, and of course I got the itch to be creative. I know that it can be a pain taking pictures during a project, trying to useful ones while trying to get it done. Really looking forward to seeing some better ones though. It looks like it turned out really good.

Cool, so you went from 69 oz to 37 so you lost 46% of the weight. That is impressive.

Before I started my quilt I thought pretty hard about starting with a Wal-Mart sleeping bag. I still don't think it is a bad idea because you can get a sleeping bag from Wal-Mart for $19.99 when you can't hardly buy practice fabric and batting at JoAnne Fabrics for that cheap.

All in about 2 hours or so of very easy cutting and sewing. The best part for me was I got to use it last summer and decide if I like using a quilt over a bag. I found out I did so once the winter is over I will be sewing a summer quilt and probably PIF this to someone on the site that wants to try quilting before they buy into it.

I will take some better photos outside in the next few days and put them up.

So I need to ask this… What is the benefit of a quilt over a sleeping bag? Like I mentioned a couple posts up, I'm new to the forum and the whole quilt thing is a new concept to me. Strictly on an observational standpoint it looks like other than a cold head and neck from no "hood", there isn't any difference. Obviously there are some, like your ability to cut the weight so drastically, but past that what is the point? I'm totally not knocking it cos there is obviously something great about them or else so many people wouldn't be making them, I'm just curious.

Thanks

The whole quilt idea was baffling to me too.
In fact it was not until i saw one in action that the advantages became apparent.
I am now a quilt user for summertime conditions myself.
The idea of a quilt is based on the fact that the insulation of a sleeping bag, trapped under your body, is not contributing to retaining warmth.
The sleeping pad you use is of incompresible foam or inflated under pressure so it's insulating air spaces are not lost when you apply your body weight.
So a quilt eliminates the "excess" material in favor of the sleeping pad which you already use as the underside.
The other advantages of a quilt I have found are how it fascilitates urination.
Yea, it's a little weird to think about but the simplicity of lifting one edge of the quilt, without even a zipper to fool with, and letting fly, is liberating.
You can also add clothing layers under a quilt without compressing the fill.
Some mummy shaped sleeping bags are cut tight to decrease the volume of trapped air and this makes them more efficient. Well adding a lot of layers from within can compress the fill from inside and decrease trapped airspace in the insulation of both clothing and bag.
A quilt can accomodate added layers simply by loosening the underside straps and provided a corner is not lifted to introduce a draft, you gain warmth as you add layers.
The other advantage is that when your quilt becomes damp or wet, there is inherently less material to soak up water than a similarly rated bag and thus less material to dry out.
Yes, you will need some type of head gear in cool conditions.
Often a hooded jacket or fleece which is already part of a hikers gear is sufficient to wear for head protection.
In my quilt I can actually roll over easily and sleep on my side, stomach, or back easily without messing with zippers or velcro tapes.
I can also wear damp or wet clothing to bed on top of my foam sleep pad and that moisture is not compressed into the fill of the quilt the way it would be with a bag only to be compressed all together in the morning when i pack up.
Some people love them, some not so much.
I am a recent convert to a quilt, but now that i have, I am not going back at least for summer time use for the reasons listed above.
#1 reason=peeing freedom (of course that assumes you are using a tarp as well! crikey!)

Thats actually a good question. I think there are two advantages of quilts.

First they're lighter than a comparable mummy bag. Now of course there are some limitations that come with this lightness. I need a warm hat to sleep with my quilt and I normally have it inside a bivy sack which helps hold it in place and keeps out chilly drafts. With a hat and bivy its no lighter than a mummy bag, sorta. Its not a lighter system but the bivy is something you need anyway (if you're tarp camping which I am), and the hat is multiuse since I wear it in the morning and evening anyway.

Second a quilt is more flexible. You can cinch the straps tight and bring it close to you for warmth. You can also expand it out and wear bulky clothes to bed in cold weather. You can also open it up a bit and make it cooler in warm weather.

By the way thats an awesome project you did there! I tried this once with a 2 pound 40 degree bag. It went down to about 19 oz but the demensions were wrong. I shortened it a bit and it just didn't cover me. So it became my little brother's quilt until he outgrew it too. Good job doing it right the first time!

Well if we are being honest, mine came out a few inches short as well but still useable for my 5'10" length. Probably perfect for someone 5'8" or so. Maybe keep that in mind for others thinking about the conversion, come up with what length you think you should cut to and then add about 3-4".

Great ideas pop up here everyday, and after I saw this thread I went ahead and converted a 3.5 lb Women's Long Lafuma 25* bag (6'6" long, didn't know they made women's bags that long). After seam ripping out the zipper, bottom, and 15 oz. cotton-feeling liner, and cutting off the hood – I then sewed it up and added a piece of M90 as the liner with an end weight of 2 lbs !!! Went from fitting my 6'1" frame to likely being good for a 5'10" individual. I did add a bottom lock and drawstring, and a top lock to close it around the shoulders. I'll likely also sew in a foot of velcro to close up the bottom foot box a bit better.

Great idea!

We have an old bag that would be perfect for this kind of project.

Our other quilts are down and I would like to have a synthetic option. Especially if it's free.

@ matt… The idea of a quilt is based on the fact that the insulation of a sleeping bag, trapped under your body, is not contributing to retaining warmth.

So is what you're saying is that the bottom side of the quilt has no insulation? Because all the pics I've seen looks like they have filled baffles.

Anyways, I think I might turn my old windstorm 3d into a quilt for if nothing else the experience of it

@ Jonathan
Maybe we are mis communicating. There is no bottom side to a quilt and thus no insulation.
A quilt is a sleeping bag with the bottom side and hood removed but footsack retained.
At least the quilt i am using is this way.
I think other designs are as you say. Ray Jardines quilt design uses a gorgette system and you tuck the sides of the quilt under your body to secure them.
When I lay down my body is resting directly on my sleeping pad.
The quilt is draped over me and fastened with a snap and adjustable drawstring around my neck.
There is also an adjustable strap about the mid section that pull the sides of the quilt in close but not under me.
The footsack is is closed by 2 feet of velcro and two snaps and the foot end is sealed with an adjustable drawstring.
So even when fully battened down for a cold night, with the strap, drawstrings and snaps fastened my upper body from the neck to my thighs is resting on my sleeping pad.

Here is the overall shot of the modified sleeping bag.

Here is the underside where I sewed inside fabric to inside fabric and outside fabric to outside fabric up the quilt. It also shows the bottom synch.

Here is the top synch and the make shift draft collar.

That looks pretty sweet… So as soon as I get my hands on a sewing machine, this is going to be my first project. Should be in the next couple of days hopefully so I'll throw up some pics once I get started.

Thanks for the inspiration… And better pics :-)

It was my first time successfully using a sewing machine, and I managed to turn an old bag into a quilt. It was a pretty terrible job but I made it happen. But after it sitting there and me not having any more fabric to play with, I decided to turn my quilt into a vest… Or maybe a jacket if I'm feeling good after the vest is done. It kind of looks like Butt so far, but it will do the job… Here's some pics of the quilt I made and I'll post vest pics once that's done.
