Jason wrote a review of The North Face Terra 60 Backpack - 3700-3850cu in on August 1, 2009
I used this for a three-week backpacking trip through Europe. The bag was comfortable, reliable and sturdy. There were plenty of pockets, it was not too bulky, and the weight distributed evenly.
It has military-grade quality; it reminds me of my marine corps backpack.
I highly recommend it to anyone.
