I usually do not compress my quilts that much. I pack them loosely in the pack and let them conform.what is the compressed pack size? any pics showing relative size?
I put one in a small stuff sack and took a couple pics that should answer your question.
I pushed down with my hand to show that it still has room to compress.
They will come with a basic stuff sack that is 12x12 flat. I like this size because it can double as a pillow sack and does not overly compress.
