Will Robbinswrote a review of Arc'teryx Bora 80 Backpack - 4390-5000cu in on May 16, 2012
I did a 10 day 121 mile trek in New Mexico and this pack was AMAZING. I just kept packing and packing and it never filled up. I ended up with 94 lbs and the weight distribution of this pack made it feel more like 50. Only problem was that the string on the zipper broke and I had to fix it with para-cord.
