I've ordered 3 Nunataks, the first 2 where clean, and free of any down, buy my last quilt had down all over it, inside and out. I thought the same thing, that there must be a hole, but this wasn't the case.
The only thing I find strange with Nunatak, is how they ship their quilts, which is inside a Mylar shipping envlope?
You'd think something this expensive, and time consuming to make, would be better protected, shipped in a box.
They've probably never had any issues, shipping this way, and figure why change?
With regards to down coming through the fabric? My Arc Alpinist seems fine, but hasn't seen a lot of use.
Where as my Specalist seemed to be shedding slightly more down, than what I'm accustomed to seeing, compared to my(2)WM bags, which hardly shed, at all.
Both of these quilts are 1.0 Pertex Quantum, and my new quilt is an Epic Specailist size M/l(19oz) I'll be using this quilt on a 5 day trip, starting tomorrow, so we'll see how the Epic performs?
