Selling my Mariposa.  Is is an excellent pack, but it is too big for my torso.  Comes with and extra buckle for the hip belt, and the air flow sit-light back panel.   Selling for $180 shipped to you in the lower 48.  There are no issues at all.  I took it on one 4 day trip.  Thats it.

 

Here is a review.
