Black Diamond Mission
The big news with the climbing-oriented Mission 50 pack is that it employs Black Diamond's patent-pending 'reACTIV' suspension system. ReACTIV suspensions, and the more aggressive 'ErgoACTIV', are designed to allow the pack to move naturally while you're walking by adding a mechanical pivot to the frame-hip belt interface. In other words, the load is allowed to swivel.

I like that the backpack doesn't have too many straps!
