I have 90 grams of 850FP DryDown here. Is that enough for a reasonable winter warmth vest seeing as how I am an XXL in jackets?
Oct 3, 2017 at 2:44 am #3494521I have a down vest maybe 1 inch of loft. Â I wear it with a synthetic vest. Â That is good for me down to 20 F. Â The down vest by itself might be 32 F. Â With base layer and jacket.
30 inches long x 50 inches around = 1500 cubic inches. Â Maybe a large size.
850 FP down would require 1500/850 = 1.76 ounces. Â add 20% overfill = 2.1 ounces = 60 grams, plus a little more for the collar.
You could do a little more than 1 inch loft or make it a little longer, bigger around.
But maybe a reasonable winter warmth would be 2 inch loft.

Using 90 grams makes it equal to something from Uniqlo and I will need warmer than that, OK
I’ll buy another small bag of down then. I did think I had some good salvaged down here but I can’t find it
Or I’ll change the vest to synthetic so I have a LW active layer
Oct 3, 2017 at 3:34 pm #3494573My idea is that a synthetic vest (or jacket) is a good survival item. Â If you get wet for some reason, the synthetic will still keep you warm.
I was hiking somewhere. Â It was raining. Â I was a little wet inside WPB jacket. Â I got to camp and started getting chilly. Â I couldn’t really put on my down vest because it would get wet and lose loft. Â After a while I dried off enough and put on down vest. Â If it had been colder it could have been more of a problem.
So, I have a 2.5 oz/yd2 Apex vest that weighs 5 ounces. Â And a down vest that weighs 6 ounces. Â The synthetic vest is good if I’m just a little cold and wet. Â Then add the down vest if it gets really cold.
