Big TK,
I' d look for a lil' comfort. Your hunt will be more enjoyable an' you' ll stay afield longer with a good rest an' VERY good food! A thermorest pad will help a lot, I also pack an airline pillow and some ear plugs so I' m dead asleep when I' m in my bag. The wool comment is dead on. Camp shoes is also a good idea. Take good lunches and stay away from camp all day. Meet yer buddies for lunch, but get used to comin' back to camp after shootin' light is gone.
