I think a lot of people do not know what is going on here. Osprey is working with BPL to test this new pack. They gave packs to 10 M-Life members for evaluation. No charge. However, you cannot sell the pack.
Two things going on here in my opinion. First, Osprey recognizes us fringe hikers here at BPL as a viable market. Second, it is a benefit of the M-Life membership.
Apparently BPL is trying to do more of this kind of thing for members and manufacturers.
BTW, I did not request a pack from Osprey, because I am happy with what is in my closet.
