I think camo has its advantages. I wear grey wool filson or johnson wool overalls and grey wool or camo wool coat when it gets cold, whether bow hunting or gun hunting. 18 feet up in a tree my woolies blend right in with the tree I am in.

I do like natural gear camo also when I am bowhunting early season. I have video taped bucks fighting directly under my stand in bow season.

Carharts are okay but I find them kind of noisy, almost cordouroy noisy, especially in cold weather. I guess if you are stand hunting a field or open wood lot the noise isn't going to make a difference though.

The important thing is you use whatever gives you confidence and the ability to withstand the weather conditions you are hunting in. You'll stay out there longer and see/shoot more game.
