Yesterday I spent 7 hours in a tree waiting for Bucky. No joy. Temp was 8f juat after daybreak, and the highest I saw was 20, and wind less than ten mph. I wore terra max from Sierra trading post under Avery brutalgear top and underarm our wader pants. Great for sitting. Walk SLOWLY! I had a merino wool shirt over that, then a down vest, a jacket, topped with anLL Bean wool hunting coat. Bottom was wool pants under northern outdoors lighter weight hunting pants. Warm in the tree, and on the boat ride att 30 mph
