naturehike rock 60 liter pack. not quite ultra light but very light and durable. Under 100 bucks compared to other "ultralight" packs that go from 3 to 500 bucks and it only weighs a few ounces more. I've only went about 100 miles with it but it seems like it will last a while.
pros.
slim profile
light
adjust pack size for different seasons via rolltop
huge front mesh pouch
cons.
not torso adjustable
frame isn't removable
buckles seem a little cheap but not garbage
