honestly...if I was you...bring a pair of medium weight pants or some wool pants...your favorite shirt for spring hunting up in alaska and an extra layer just in case....as you could run the gamut from 75* to 30* depending part of North Carolina and what the latest cold front or offshore storm has in store. For example in 70s/60s this week but this weekend going to be 60s/40s. For me with my hot weather acclimated southern tail...that means the wool plaid shirt, wool pants or atleast medium weight earth tone pants.
like i said..that will be warm to you so prepare for what you would consider warm weather and I would not worry about camo pattern so much as long as it has bold patterns..plaid, mossy oak, real tree, predator, asat...no difference in big scheme in my opinion.
Come with your regular clothes and some light-medium weight stuff....if it is colder then go to walmart and spend $40 if you need it on a fleece jacket....if not then you are good to go.
