I am planning to make a down quilt for around 25 degrees F (-5C). I will most probably buy the thru-hiker kit (with momentum) but am considering whether to add a more water repellent strip to the base of the outer shell (around 10" wide) to limit problems with picking up condensation and rain spatter. I have some 1.8oz ripstop Epic Malibou polyester from owfinc so I would appreciate any comments on the suitability of the Epic to do the job. Having read through many of the posts on the performance of Epic I remain confused.
The Epic fabric appears to have one side somewhat shinier than the other. Which side should face out?
