I am going on a dall sheep hunt in August and have looked at just about everything out there as far as rain gear. Cabela's, REI, Barneys of ANC., all have nice (expensive stuff) that they would like to sell you and they all claim that theirs is the driest, lightest going. Maybe so....
But, I have decided to use what I already have and it is not camo'd. I snow ski, backcountry hike and do just about everything else outdoors in the winter in a North face goretex shell jacket with a polarfleece zipup mock turtle neck and have never been wet or cold. It is light weight and the moose said they like the color pattern of black/blue. I use polarfleece long john u/w bottoms and a helly hansen guide pant that zips all the way from the ankle to the hip for easy on/off and cooling. They are black. Most of the animals are color blind anyways so it doesn't matter if you have camo or something you already own thats not. I guess you might impress the other hunters at base camp with your new MT050, etc, but other than that who cares. Good luck in your search.
