Im gonna get al kuiu pack this summer.
I am running an eberlestock j34 I am hiking some miles every day with 60 pounds of sand in it. It carry's that weight good. I have other eberlestock lacks so I knew I would like it. If money was no object I would go kifaru. Also look at exo mountain gear,mystery ranch and tenzig. Kuiu and sitka both make packs. Most important is fit. Go to rokslide. Com alot of info on back country hunting.
Im gonna get al kuiu pack this summer.
Also add stone glacier to your list.
I knew there was a good one I for got. I have also heard seek outside packs are good
I have an Eberlestock for sale if anyone is interested.
