Anyone who has followed along with Aron for any amount of time, knows he really got his start in the industry testing and reviewing all kinds of gear, very specifically backpacks.  Putting all brands thru their paces, he shortly there after went to work for Patrick Smith and Kifaru and the rest is history.  Now that he's a free agent again, he went back to his roots and gives his best unbiased review of 4 of the top pack companies on the market: Kifaru, Mystery Ranch, Initial Ascent, and Stone Glacier.  Each one has their strong sides and short comings, but we try to provide a comprehensive review of each one. But Im sure we'll get some comments either way!
