This little backpack is the little bag that could - it's lightweight and a bit smaller than any other travel bag I've purchased.  That means it fits perfectly on my back without being bulky and still giving me great storage.  I'm a lady of average weight and about 5 ft 6 -- my husband (6 ft 2) wore it occasionally and it worked for him too, but didn't seem as proportionate on his larger frame (read:  probably not a great dude bag).

The straps aren't super padded (like some gel straps I've used before), but are more than comfortable - even when carrying a couple of water bottles, DSLR camera and other random travel items there was no chafing or discomfort whatsoever.

What definitely sold us on this bag initially were the Pacsafe safety features (zipper lock, locking bag strap for mealtimes at a restaurant, slash proof mesh lining, RFID protector pocket).  Talk about peace of mind, it was nice being able to focus on my young daughter as we traveled in Central America - rather than worry about the guy behind me on a crowded walkway being able to easily access my bag.

The biggest surprise about this bag was how darn nice the material is - the black fabric really feels high end and looks beautiful, while staying super durable.  Weird to say about a black backpack, right?  The green polka dot lining is cute and helps you locate those annoying bottom of the bag items at twilight.

Great little bag - we'll definitely be buying more Pacsafe products in the very near future (if you're looking - the Pacsafe Metrosafe cross body bag is amazing too).
