Redesigned for thru hikers and long-distance backpackers, the Unbound 40 and 55 are lighter, stronger, and more comfortable thanks to an updated build with the exceptionally durable Dyneema® Woven Composite 3.9. Two contoured removable stays, a refined hip belt, and wider, more naturally curved shoulder straps improve support and comfort

Unbound 40
Fits well, I like the new shoulder straps. The ability to remove the belt and two support stays is nice. New dyneema is amazing (quieter, lighter and feels stronger). I feel the straps slowly loosen over time in sternum and hip belt so you need to retighten now and then. Overall I like how it carries weight and is more trimmed down and streamlined. I’d recommend it to friends/family

Unbound 40
Very comfortable and roomy enough for my essentials. I haven't used it in the pouring rain. That will come in November. Hopeful that it will be waterproof. I think it will be.
