If a manufacturer would produce quality duck gear in that old canvas brown, I'd buy it instead of camo for sure. I bet a lot of other old guys would too. Maybe it's just nostalgia, but I'm sure it would work every bit as well as the current camo offerings. I don't think many birds flare from your clothes anyway, it's your shiny face or motion normally. Remember the snipers rules of concealment...shape, shadow, shine, silhouette. If you're in any kind of blind you probably have three of four covered.
