I have already hiked the AT in 2013-2104 and used the ORIGINAL Osprey EXOS 58 backpack. This backpack has been updated to better padded shoulder straps and hip belt. Osprey also removed the 2 exterior back pockets with the update (which is a real bummer). When I did my hike, the trampoline mesh backing and mesh hip pockets wore out and tore. Osprey replaced the pack 2x during my hike (free) because of this issue. I'm heading back on the AT and would like to know if any of you have had any issues with the UPDATED Osprey EXOS pack. Thanks in advance.
