Homemade down bag on 03/22/2007 10:17:51 MDT Print View

I am looking at making my own down sleeping bag. I was going to use 600 fill down.

I am looking at about 20oz of fill... what temp rating would that put my bag at? I am looking for something around +10 or +15

would this be about right?

600 fp *20 oz= 12000 ci.
A lot of 15* bags have about 3" of single layer loft.
What are the dimensions of the bag you propose to make? As long as the bag has around about 4000 ci of area you should be ok.
It also depends on whether all of the down is on top of you (the optimal place for it, like a quilt) or if you are sleeping on top of some of it (like a sleeping bag, where the down underneath you is compressed and does no good).
A little more information might be helpful so we can get a better estimate of what exactly you have in mind.

The dimensions will be 30" x 80" mummy.

It will be a sleeping bag so I will be laying on some down. I am using a write up off of the homemade gear site I googled.

I will also be sleeping in a down jacket in a HH if that matters... I am using my Northface windy pass as an onsite pattern.
