Summary: The bag is waterproof, although water seeps in around the lug holes at the bottom, but doesn't get very far. The size means you chuck more equipment in than you realistically need, but that's not the bag's problem.
Pros: Waterproof - has stood in a foot of water in the sea., Built to last - used and abused it for eight years now., Looks good - also used as an overnight bag...
Cons: Could be quicker to open, like the 445, and it could use more closed pockets and pouches, but that's it.
Summary: This is the ultimate soft camera bag at a price which is justified by the quality of manufacture and the protection it gives to valuable equipment. It swallows huge amounts of gear and you can pack EVERYTHING if you cannot decide what you can leave behind.
Summary: I have bought bag after bag, you name it I've bought it. Never could warrant the cost of this flagship bag...how wrong was I...I've spent 4 times as much on bags that have fallen to bits, too heavy, too small, too large etc etc.
Pros: Comfortable Strap, Durable, Good Protection, Lightweight
Summary: Bought mine well over twenty years ago and it's still going strong. Well battered but has never needed a repair. There's only one thing to watch out for, it packs so much gear you can end up looking more like Quasimodo then a professional photographer.If you can afford it, buy it!
