I have been using them for a couple years now. I am pretty religious about scent control and use the silver max as a base layer. I have the lightest set I believe and wear it as long as it's not too warm. If it's pretty cold I'll put on another layer or two of other clothes over top. Like I said, I am reigious about scent control and try to play the wind to my favor. That being said, I'm finding it hard to remember the last time I was winded by a deer while it the stand. I don't now if any of that is attributed to the Medalist Silver Max layer or not, but it's working so I don't plan on changing what I'm doing.
