RE: before I buy.... your thought's on scent-lok
I've always been a big advocate of the Scent-lok suit. I've had deer within several feet of my stand, downwind from me, and never I'm there. But, as mentioned before, you have to make sure that your body is as scent free as possible. Take a shower with scent free soap, make sure all your under garmets are washed with scent free detergent and spray yourself and each layer of clothing with scent killer as you get dressed. I also wear rubber knee boots with scent pads on the bottom.
The only drawback I've heard about the Scent-lok suit is that your dryer has to reach a very high temp to activate the charcoal in the suit? Can't remember what the temp was, but I do recall that it's higher than most home dryers can reach?
