i have tested a prototype with differential fabric on the long side, at 2" per.
so now, the top layer on a Freeze is not only 6" wider than the bottom across the width of the uq, but also it is now 2" longer, along the length.
i have noticed this does two things.. first, it forces the uq into a very slight curve, about how you would lay in your hammock.
second, it allows more loft in the baffles, with almost no noticable compression of the down*
im considering offering this as standard or as an option with the quilts containing overfill. id like to see what the customer thinks as well. let me hear your thoughts!
*down has been tested to show that even with a 50% compression, it retains the same warmth.
