What packs are all you gram weenies using?

18 oz (if you want the side zip, it adds 2 oz)—I think that's in 200X which is probably an ounce-ish lighter than the Ultragrid

Holy cow. That’s 20oz lighter than a K4 5000.

Has anybody fit one to a K4 frame?

I have the Arc Haul 60L and I wouldn’t trust much weight in it past 35lbs. I have used on 2 20 mile Appalachian trail hikes and it appears to be separating at the seems. I plan on just running a Kifaru no matter if I am hiking or hunting.
