|The North Face Terra 65|
|Maxpedition Falcon II|
I've slid down frozen gravel hills on this pack, I've caught it on numerous tree limbs and I've tossed it around a good deal in and out of my jeep and it has zero signs of wear after 3/4yr. of use. If your looking for a bullet proof day pack and dont mind the extra weight you'd be hard pressed to find something better. They also make larger packs but since their gear is more military orientated expect over engineered construction and heavy weights...no silnylon or cuben fiber here.
