Very good pack
I do love my Naos 45. I got it about 3 years ago. It fits my torso very well. I am 6'5" and the tall works great. It carries loads quite excellently. The swively bit, and the hip load distributer in general is great. It just works with my strides so well. It is pretty water resistant. After a recent 15 mile hike in the midst of all-day often-heavy rain: the pack was only wet inside to the extent that i placed wet items inside. Very nice.Here is the only downside, so far: the taping or whatever on the left-hand (large) exterior pocket has disintegrated. It did so not too long after I got it. The other zippers have held up well. I contacted Arcteryx recently about this, and they said to ship it back for them to check out. I haven't done so, yet (can't be without my pack! hehe), but this seems like great, personal, service.
