No pictures of the packed down size?? How did this make it into the UL category with the most important factor not being addressed?

You know what would probably sell better? The Massdrops UL Quilt :D which is 10oz lighter for the same EN-rating, and $50 less expensive. Bring back the Massdrops quilt!

hardcorehikerThe Specs list the "Fill weight" which only refers to the down. So that answers your question, but looking at it again from your view I see how we could make that more clear since there is down and synthetic, each which could have a fill weight listed. I'm not sure we'll be able to find the synthetic fill weight but I'll ask our friends at Marmot.

I wonder what happens to this bag's performance in the long run, once the synthetic fibers start to break down while the goose down lasts much longer. I suspect the synthetic insulation will just be dead weight.

jari.perhoI suspect not. As the Synthetic fibers are mostly under the body, even Down there is dead weight; and as Synthetic fibers remain some insulation properties even as they become old and lose loft, I guess the difference wouldn't be that great.

jari.perhoWell they'll certainly break down with time as all synthetics will, but in this application of bottom-only I don't think that would be an issue or lessen the effectiveness of its purpose like it definitely can on the top side of a bag. Whether insulation on the bottom of a bag is truly dead weight or not just depends on the pad and of course too much of it is just wasted. A thin layer does provide some additional r-value no matter the pad but it has more value when you use a pad that has some gaps that can be somewhat filled in, like the Sea To Summit quilted surface, the Klymit v-style, or even the Klymit open-hole designs. A little comfort value, too. I had an old Mountain Hardwear model, full synthetic, that used just a very thin layer on the bottom and a full 20 degree layer on top...worked well, saved some bulk, smart design with a little more warmth than a typical quilt or Big Agnes style sleeve.
