the backpack

What do I want? a big pack? a small pack? a heavy sturdy pack? a light flimsy pack? an expensive good quality pack? a cheep affordable pack that will do the trick? what color? what brand? how many pockets? looks or comfort? Is there one backpack that I will be fully satisfied with? Am I just too fussy?

The North Face Terra 40

I bought this one a few weeks ago, was told to try it out, pack it up with stuff i will need for my trip. I guess I didn't mention how long the trip was for...I still don't even know myself. It was only a 40 litre backpack, but a very good quality north face pack. It was 140 bucks plus taxes. it could fit 5 t-shirts, 1 rain coat, 1 hoodie, 1 pair of jeans, some socks and underwear, bathroom junk, a few pair of shorts, and then i realised, wow it could be all i need but, what if i buy stuff over there. so I quickly decided to return it. Need to keep searching, possibly EBay or other online stores for something near the 150-200 bucks with shipping included.
The hunt is on
