Personally I own a scentblocker suit and wear it every time I'm on stand. Does it work? well I can't say for sure since I can't smell as well as a deer. What I can say is that it gives me extra confidence while I'm hunting and I do believe it offers a slight advantage over conventional clothing. However, I still select stand location as if I'm not wearing one. I don't use it as a reason to not hunt the wind but rather an added piece of protection should the deer come in down wind unexpectidly.
