cabelas extreme stand hunter or berber fleece
The drawback of the berber fleece is that it picks up any debris within 5 feet of your trail. You will spend a lot of time pulling burdock and other seeds off of you ,long after you get settled in to your stand (gives you something to do on those slow mornings, I guess).
I would highly recomend it on cold days if you have an easy walk in to your stand. I will recomend the vest as it keeps your core warm and still frees up your arms.
