After years of trial and error with nearly every brand of backpacks (local and international), I rarely deviate from buying JanSport (and sometimes Targus, REI and Colombia).  This little guy seems to belong to the same category in terms of style, functionality, versatility, and durability as Colombia, although I haven't quite put it throught the stress test (heavy load for 2+ years of abusive use).

It's longer and roomier than my old Colombia sling bag, which was very typical of most sling bags in the market.  Unlike the Colombia that allowed for switching the strap from one side to another, this one has a fixed strap (center at the top, to lower left on the back).  Nice padding on the back, with plenty of pockets have made it my most frequently used bag on day to day basis.
