First shot at a down UQ

[JohnSawyer]

So.... can we BUY the high-quality down -and if so from where?

800+ FP down for $6.50/oz here: http://www.hammockgear.com/cart/inde...products_id=10

or 900fp in bags of 3.1oz for $35.00 http://stores.tttrailgear.com/-strse...ion/Detail.bok

Okay


What weighs more.... a pound or feathers or a pound of lead?


So is this an ounce of weight or an ounce of volume?

how many "ounces" can i expect to use in a 4'x4' UQ with 9 baffles?
Or maybe I should ask this:
How much volume can I expect to get out of one ounce of down?

Fill Power: #of cubic inches 1 ounce of a down will fill. Typical to find 600 in sleeping bags, etc. really good stuff is 900. The higher the FP, the smaller the article will ultimately compress, too...

@ Convert2010,
I think this would be 1 oz in weight. So 1 oz (in weight) of "900fp" will fill 900 ci of volume. Thus the higher the number, the smaller/finer the individual down feathers are. Therefore being lighter weight per volume and also being able to compress to a smaller space.

So, if my math is right.

my 4' x 4' UQ is

48" x 48" x 2" (of loft) = 4608ci
so... I will need:
4608 / 900 = 5.12oz of down

The math is right, I bet that will net you a UQ thats less than 16oz.

Don't forget to account for the "bulging" of the quilt. It's sometimes referred to as overstuff.
