This pack is a medium pack with medium belt I bought in late 2014.  The original owner claimed it was an unused early 2014 model that he purchased in July of that year.  I’m not 100% sure of the GG model year changes, but it appears to  be the same as the one reviewed here:

The pack has had light use.  The only flaw I can find are a couple of small holes in the front pocket mesh (See pic).

Asking $150 for the pack.  Shipping to the lower 48 is included and I’ll cover the PP fees.  PM me if you are interested.
