If the wind is just lightly blowing, I hang it on a limb on the upwind side of me. If the wind is blowing too much for that, then it is probably blowing good enough to keep the bugs away.
As far as using it when still hunting, that would be hard to do. In order to be effective, it needs to be sitting horizontally so that the air rises through the scent pad. I have a camo "holster" for mine. I could possibly hang it underneath my backpack, but it would bounce around. I wouldn't want it really tight to me because the head does get somewhat warm.
