I dress extremely light walking in. I carry a climber with a backpack strapped to it. Backpack has all my stand clothes strapped to it. I look like a homeless person with everything I own strapped to my back. I just wear lightest weight silky base layer, t shirt, vest and regular camo pants, and non-insulated boots. I don't get sweaty on the walk. I make sure of it. Once I'm in the tree, i put a lightweight insulated jacket on and (if it's cold) i have a "Warm Bag". It's like a 3/4 length camo sleeping bag with denier on the bottom where your feet are and suspenders. It is best thing i ever bought for hunting. Keeps my feet and legs warm and covers about halfway up my torso. I rarely get cold, but noticed this year, on windy days, I got pretty cold. That's why i decided to upgrade on the vest.
