I just revisited this thread and am a bit surprised at the fuss.
Yes, in 2011 I bought at my local Costco a $40 down kirklands jacket exactly like the 2012 photo posted by this thread's OP. Bought it, took it home, compared it to my First Ascent jacket , kept it about a month & reluctantly returned it since the FA already covered my needs. Mine was black; IIRC the other options were blue and green, neither in shades I liked.
All the observations about the 2012 jacket also are correct for that 2011 jacket, including weight. I had a men's XL which fit me well at 6.0 and 180. It was NOT a child's jacket, although I believe the posters who say those are also good buys.
I agree someone at Costco is, happily, interested in offering some good quality technical gear.
So far this year thatvsame Costco branch has not had any men's down products, although they have had the $30 women's down mentioned elsewhere.
Part of Costco's success formula is focusing their store demographics. Of the two Costco's near me, one is noticeably upscale ( where I found that 2011 down jacket) and the other trends much more blue collar. They will have very different offerings in apparel, electronics etc. Products also only get a short rotation life: badabbing, some items are only there 7-10 days and gone. Most of their product lines, including apparel, never appear in their online catalog--this is not REI or LLBean with long product lives.
As for why the same jacket was in one of my Costcos last year and again more widely in 2012, my affluent outdoorsy East Coast store could have been selected for test marketing to gauge demand or was just deemed more likely to respond to a Patagonia knockoff.
I liked the 2011 jacket a lot BTW and would have kept it if I hadn't already had the FA jacket. The Costco jacket was packable, not under filled to my eye, had good long sleeve length as it should, and was cut to layer well. Outer shell fabric less luxurious than the FA (doh) but nice enough and felt reasonably durable.
