I have a sleeping quilt, a make-it-yourself quilt, as shown on Thru-Hiker web site. It is made of 1.1 oz ripstop and 2 layers of .8 inch Primaloft.
I can easily roll-it up to the size of 9 inch diameter and about 20 inches wide. If I used a compression stuff bag, what size should I get ????
What size and brand stuff bag should I use ????
For a thru-hiker quilt stuffed with down, I use a 14"h x 10"w stuff sack with a 3" collar. It is 22" around the middle (circumference) when full. A size small compression sack from Granite Gear, measuring 10" x 16", and with a round bottom, compresses the quilt to a ball 24" around the middle, 26" around the ends. Assuming the primaloft does not compress quite as small, a 12 x 16 stuff sack would be good. That's what I use for a Ray Jardin design quilt with primaloft, but rectangular in shape. From Ed Speer's book on Hammock camping, to get a 10x15" sack, start with material 20.5" x 16.5". I would recommend building in a collar, so allow for that. Use a felled seam instead of a striaght seam, and put a gromet into it for your pull cord. The Granite Gear compression sacks are light, probaly silnylon, and you have to waterproof the seams. The small size would fit your quilt.
