M50 quilt on 05/20/2012 08:55:25 MDT Print View

Well, finally found some extra time yesterday to sew together the quilt I've been meaning to make for some time. I wanted something that would be a versatile bag, that I could use for all 3 seasons.

I decided to just sew my own, and went with Thru-Hikers kit. With 12oz of 900 fill down, I was expecting this to be good to at least 20 degrees.

Dimensions of the quilt when layed flat before stuffing was 84"x52"x40". At 6'0, I wanted to make sure that after the drawcord footbox was pulled tight, I would still have room to pull the quilt over my head.

Sewing was not too hard. I have to admit, the though of sewing a down quilt sounded hard at first, but a little reading went a long way, and I had no problems sewing. Baffles are tedious, but made a lot faster by the technique outlined here:

Baffles were sewed to have a finished height of 2.25in, and stuffing was calculated at 2.75 in, making for roughly a 20% overstuff. Omni-tape is used for the footbox and head closures. Drawcords run through both the top and bottom.

I was very happy with how it turned out. When layed flat, loft is a whopping 3 inches in some places, although I would say in most places it is 2.5. This should get me to 20 degrees with no problem at all. I'm a warm sleeper, and I expect that with the proper pad, 15 degrees would not be out of reach with loft like that.

Finished weight is 18oz in the cuben stuff sack. It stuffs down to a ~14"X10" stuff sack quite easily, without compacting the down too much. I dont like the compression sacks that turn bags into rocks, I want this bag to last for a long time.

M50 is a great fabric, and once again makes me like it even more. A downproof fabric that weighs .69oz a yard is amazing. To top it all off, M50 is very very water resistant, which should help protect the bag even more. I probably could have used a little less down (9oz) and saved a few ounces on the finished weight, but I wanted something I could take earlier in the spring and late in the fall, and I figured if I could have one bag that could do it all, I'd prefer that over two different bags.

Finally, some pictures. I apologize beforehand for the bad quality of the pics, they are from my phone.

Looks great.

Think you'll still be able to sleep under that warm beast during warmer weather? Or is it just for colder nights?

That's actually what I'm wondering as well. I decided to go with the drawcord footbox, I figure in warmer weather (warmest it ever gets at night where I backpack is 40-45) I'll just undo the footbox and lay it like a blanket on top of me.

Looks great. Few Q's. So what's the deal with the no see um baffles that people do? Any purpose? Could your quilt be made without using a vacume for the down?

I've done down garment.

You need to weigh down for each baffle so it is uniformily lofted

I just grab down from weighing container with my hand and compress into a ball, grab down between fingers with other hand, stuff into baffle, push further into baffle with rod

Vacuum system would maybe be better if you had a lot to do? But for just one or a couple garments by hand is fine? Maybe by hand is fine even for large number of garments?

Like Jerry said, the baffles just keep the loft at a uniform height. Without them, the down would clump into piles and create cold spots.

I didn't use a vacuum for this project. Just stuffed it by hand. I put the entire bag of down on the scale, and calculated how many grams were needed in each baffle. I then just subtracted the amount needed for each baffle from the total weight of the bag the down came in. Yeah, it was a little messy, but I wasn't even being particularly careful, and all the down I swept off of the floor only weighed about 2 grams. Just make sure that all windows/doors are closed in the room you are stuffing in, and you will be fine.
