Is it the same as this one?

I bought one recently and it's excellent, the condition was almost like new.
The main advantages - it packs a lot of gear, is water resistant and has loads of different compartments, very comfortable and multi-adjustable shoulder straps, it's frameless.
The main disadvantages - the waist belt is narrow and not much cop, it's not the lightest on the market (nor the heaviest I suspect) harder to pack as it's frameless.
I've still not made my mind up about the lack of a frame, there is an internal bar you can grab hold of to aid packing/stuffing... price is very keen for a 60 litre sack.
