I just usually buy military style BDU's because they are comfortable, and most importantly durable. They are just usually camo. My dad is cold a lot so he had fleece lined jeans, and an insulated flannel shirt. A buddy of mine wears tan Carhartt Overalls. I don't really buy the camo for a purpose, but the appropriate clothes are often given a camo print. Missouri requires a the orange during rifle season.
