>> Nasty color
Hehe, I've got to agree about some of the Patagonia colors. The Lagoon Blue isn't so bad though, IMO. The down shirt used to come in a light grey back when it was originally reviewed by BPL, but alas no more.
At any rate, if you don't mind the colors, the down shirt is a really nice mid-layer. At only 5.6 oz for the medium, it saved me roughly 5 oz versus a fleece hoody.
