Don't get me wrong, they could be fantastic quality, but I suspect with the internet being what it is, there'd be a raft of reviews/blogs/recommendations for it.
That they're upfront about it being made in Vietnam, but designed in the USA (plucking at the patriarchal heartstring), is to be lauded, but $449 for a bag!
At least Apple have a strong share price, happy investors, and a nation's economy being propped up by their profit margins.
So either they've not negotiated too well on the manufacturing front, are coining it in, not keeping their overheads in check, or simply buying in low quantities.
If the latter is the main culprit, then it's understandable the margin's not there for distributors/resellers or quantity for them to supply at a moment's notice.
No-one these days, unless there's really something there to capitalise on, will be looking to act as a partner by giving them a big order that they're having to front or will take the (small) manufacturer too long to complete.
Bag looks ok, imo, but not worth anywhere close to the asking price.
In fact, I don't even see the worth in the others I've suggested - even if low volume production is being used to justify it.
But, as you're contemplating spending that sort of money, have you thought about
http://www.photobackpacker.com/home.php with a view to asking if they could customise the cases for equipment?
If that worked for you, I'd opt for longer cases, with dividers, so if you change lenses, you'll not need to buy a new case specifically for it, each time.
Two other contenders - but may still need to be personally imported:
