It seems a bit unfair to call the South Col a fantastic expedition pack: the flexible design concept makes it more like a set of expedition packs!
To begin with, it's tough, lightweight and supportive, just as you'd expect. As well as that though, OutDry construction sees a waterproof membrane bonded to the fabric for a level weatherproofing not normally found on any rucksack.
The aluminium stay around the perimeter of the back allows pivoting while still transferring weight to the belt - a real boon for the mountaineer - and the HardWave framesheet further spreads the load while conforming to your shape. Pitch camp and unload your stuff though, and you can remove the framesheet, swap the hipbelt for a lightweight webbing strap and pop off the lid pocket: you've got yourself a lightweight pack for moving between camps and pushing to the summit.
So, really, you've got a minimal, stripped down pack for lighter cargo, and a fully specced load-hauling monster - both in superbly tough waterproof fabric - even though it's just one bag.
