As someone noted in the Gear Forum, Costco has been stocking the "Stuffable Down Jacket" again. It's under a new brand name and stuffed a little less than last year, but is the same product. It's an extremely-lightweight-skinned down jacket with a hood.
The sizing on these was a little weird last year, so it's best to try this on. It's not just that it's Youth-sizing, but that their "medium" (for example) doesn't correlate to any other youth medium. Short, little stubby, miniature adults will probably fit in the Youth XL.
Several of my Scouts use these, and I recommend it, regularly for those who fit in it, as part of a layering system. It is NOT suitable for a daily-wear jacket, as the shell is very thin.
