Michael L.wrote a review of Arc'teryx Naos 70 Backpack - 4270-4640cu in on March 5, 2009
I think I was one of the last holdouts in the world on my external frame pack. I loved the rigidity of the frame and the ability to tie things to the frame. When I finally bought an internal frame pack I knew it had to be a good one. When I saw that this one was water proof and had the disc system for weight dispersment I bought it. I no longer get the aches in my joints that I used to and the pack very waterproof. Only thing I will say negative is that there is not much air ventilation to your back. Overall this is worth the money!
