First post on here although so be nice

I have followed this forum for a while and have always found the posts to be very interesting.
Anyway, the question I have for you today is does anyone know of a down jacket that has removable sleeves?
Coming from a warm climate in NSW I think I would still get a bit of use out of the down vest in winter but for hiking and traveling in cooler climates I know the jacket would be ideal (I am planning on climbing Kili this year so i know the jacket would be very handy).
I would have thought a design like this would be out there somewhere but apparently I am missing something! The only thing close that I have come across is this snowboarding jacket but its not really what I'm after - http://nomisdesign.com/products/Mens/Fa ... %20Jacket/
Thanks
