I've heard that EightD (previous name) had some issues with leaking and I'm very much on the fence between this and M90.
So far so good, before making the quilt I made a pillow to test the fabric out...Some small bits of fluff at first but no full feathers, I'd say Down resistant not down proof. I dont have any experance with M50/M90 so cant compair but I am happy with Nobul1 so far...here's the pillow post
