All in all I am not too impressed with F/W 2012 from Gant Rugger. I am biased, of course, since I own so much from last year's collection, but I think the new versions of last year's stuff are, for the most part, inferior. And a bit more expensive, if my memory serves me correctly.
Homerun 2010 > better colour (and so, so much cheaper) than Homerun 2011.
The toggler 2010 > the toggler 2011 (can't stand the white poly blend lining on the 2012 version, looks cheap IMO, also doesn't have the plaid lining that is one of the nicest things about the 2010 toggler for me)
Hiker parka 2010 > the rain coat 2011/the other parka which I can't find on the gant site atm
Boucle Sweater/Argyle sweater 2011 > any of the sweaters from 2011
There are a couple of nice things, but nothing in it screams 'buy me', which is good because I really don't need to buy any more Gant Rugger stuff : http://www.styleforum.net/t/166748/the-official-gant-thread/105#post_4697913
And a shameless plug that my Hiker Parka is currently going very cheaply on B&S:)
