I like to keep my clothes and boots in a bag with fir limbs for hunting in my area. It is not about removing my scent, it is about minimizing it. I hunt a lot of areas with swirling winds out here and have had deer get a short whiff of me with the fir cover scent. The perked up looked around and went back to feeding. On a strong or steady gust towards them they blow out of there no matter what. For me, I use descenting soaps and the fir cover scent to give me a small edge.
It is all about reducing the total impact I make in the woods. Sometimes the wind gets you and if you have minimized your scent you can still move in and make the kill. Does it help, in my view yes. Is it a cure all? No it isn't. Playing the wind is still the most important factor in scent control. If I waited for a steady wind I would never hunt in my area.
