Down, over-stuffing, to baffle or not to baffle, etc

This thread may belong more in MYOG?

The only thing I would remotely think of doing with the Costco down Blanket to increase the warmth is to buy another one and taper it length wise from 40" at the top down to 25" at the bottom. Then just sew it on the other centered so the excess covers you (for the most part) with a second layer.

Hi Aaron, thanks for the suggestion. Seems like it would add a lot of weight (plus my local Costco doesn't have any left). I may just add the 2.5 oz Apex with UL nylon as the face fabric since i have some Apex lying around that i'm not using. With the Apex, it would make a decent Fall quilt, which i will let a friend use.

What did you end up doing?

I seam ripped one direction so I have fewer seams and more warmth.

I opened up the baffles and added down from a donor blanket. It helps but the cold at the sewn threw areas is the problem.  I think a small double layer section with over stuffing is the way to go.  I’ve got some plans for a small torso width double layer but haven’t made it happen yet.

I’ve mostly left it the way it is, except that i sewed it up about 1/3 the length. I plan to use it in conjunction with either my 25 degree quilt or 0 degree quilts on colder days (or rather let my spouse or friend use it to boost one or the other).

I came back earlier from a weekend trip where i used the costco quilt despite that the lows forecasted was 28 or so. To supplement, i wore a down vest, and light down jacket over same, and used a double silk liner that has a little Apex in between the liners (which i didn’t do a very good job of stabilizing and it mostly got bunched up near the feet).  Regular pants though.

Reasoning was that i let my friend use the 25 degree quilt, and i figured i would roast too much in the 0 degree quilt.  I sleep pretty warm.  But after we got to camp, i kind of worried a bit about my set up.

I was actually fairly good until around 2 or 3 in the morning, then i started to get a little cold and uncomfortable. Still slept a little off and on after that, but wasn’t entirely comfortable.

Funnily, my friend, whom is a guy, was complaining about being cold in the 25 degree quilt, and he also had on a down vest and jacket (as well as Cap 4 hoody and nylon button up shirt under these, and a windshirt over it all).  I told him, being a newbie, that he definitely sleeps cold.  I would have been overly warm with all that on and under that quilt.

Considering the Costco quilt is like a 50 degree quilt, i’m surprised i wasn’t colder.  Guess the combo of down vest, down jacket, and double liner helped a lot.  We slept in an AT shelter, which i don’t normally do anymore, but i don’t have a good and easier to set up UL 2 person tent and he doesn’t have a single tent.
