If they bowhunt, the cold weather gear can be used rifle hunting as well as Mildot pointed. I however, subscribe the Outline Breakup philosophy of camoflage, not the "Oooh pretty" </Homer> patterns that Realtree and Mossy Oak put out.
They look great to our eye, but I find that at longer distances they turn into dark masses. That tends to ruin its ability to break up an outline. I think some people wear it because it looks snappy and is nice and warm.
I dont do any of the duck/bowhunting, so I really cant afford to buy pricey winter camoflage. If Im after coyotes I have slips that fit over regular winter wear. I go with regular winter garb to stay warm out deer hunting. It blends in just as good as printed camo, as if that becomes a factor with your big blaze DONT SHOOT ME coat
Works well enough, the lighter green pants blend in great with the sage of the area. Just need a coat thats not Blaze orange or black...
