A solid performer!
I've carried some heavy loads in the Bora 95 over the past eight years on trips raging from a few days to almost two weeks. You can't go wrong with this pack.
A note on the rain issue. I packed mine full of sheets and old clothes and did a three hour hike in the rain. After returning and checking the contents, I found a few areas wear rain had found it's way though openings. This was a steady rain, and I never noticed a problem with brief showers while on treks. I purchased the pack cover which I now throw on (easily) when the weather takes a turn.
Last year the straps started to tear. I contacted Arc'teryx directly. They replaced the straps at no charge. Very good customer relations!
