I used this for a karo step top quilt using calendared 1.0oz HyperD for the shell and 0.67 noseeum mesh for the baffles. All materials purchased through RSBTR.
First, the packaging. The down comes super compressed in taped up ziplock bags that have 3 oz. a piece. This is really great when it comes time to fill your project. Because I used the karo step technique I was able to get both hands inside the quilt and open the zip lock bags one by one and start distributing the down around with my hands. This made it much easier and I had very little down to pick up out of the tub when I was done.
By comparison, I made a top quilt for my wife using down I purchased from Amazon that was supposed to be 850FP. Her quilt was slightly smaller in dimensions, and I used one ounce more in hers of the Amazon purchased down. There is no comparison between the loft between my quilt using the RSBTR down and the down from Amazon. The other one SHOULD have more loft since the dimensions were smaller and there was a little more down, but the opposite is true.
Get the down here. Don't get tempted by cheaper prices elsewhere, you will NOT get what you think you're getting other places. Get quality products from RSBTR.
Down came in a heavy ziplock gallon bag with a small pin hole. No obvious feathers that I can see in the mix, although I am afraid to open the bag until ready to use it to add to my EE quilt that has cold spots.

Great product, used it to make my own hiking quilt. It's super warm and VERY light.
Worked great for winter top quilt.
