This a great backpack, good support, plenty of attachment point, good capacity, good weight for the quality. I’ve used it an many Grand Canyon trips and don’t see any sign of wear on it.
Good for a week on the trail if you pack good.
Only Con: Top compartment is only logical place for a bladder, which is convienent, but doesn’t work well with rectangular bladders. A 100oz bladder will barely work, but 70 fit’s nicely.
