Labman,
I have lived out here in Southeast wyoming for the last 4 going on 5 years. I came from Ohio so I faced the same issue you are facing. I needed clothes and Mossy Oak breakup just didn't cut it out here
I was reading all the forums, and talking to people out here. but I decided to wait a year and see what I needed. I like to go back in for 2-3 days hunting into the wilderness areas or at least 3 miles back from the nearest road. You don't seem to find as many hunters that way. I honestly didn't want to spend $200 bucks for a pair of pants. After being the first year I sort of figured what would work with me, and this has served me well.
Nice base layer - went from cheap sportsman warehouse thermals to merino wool
Pants & Shirts - I like Predator camo pants. Great camo, not real expensive and works.
I use a Vest or fleece pullover for extra warmth and carry a cabelas oufitter coat for when it gets real cold or if I am sitting glassing. Get the one with wind shield
If you are set are a "system" and wanted top of the line, I think KUIU is the best. If you want good without breaking the bank. Russell.
Now I know there are guys on here who will call me crazy and swear by the systems. I guess it boils down to what you will feel comfortable with.
