After watching many of the TV hunting shows it occured to me that even though guys like the Drury Bros. who have all the bells and whistles when it comes to scent control still do not hunt stands where the wind is not right. That tell me a lot about the stuff. However, I do have some of the clothing. I got it through Sierra Trading post and it is very well made clothing and STP prices are pretty good if they have your sizes. Up here in NE the slightly heavier weight of the clothing is like wearing a sweater and that helps on cool days. Another benefit to the scent lok stuff is that it makes a very quiet wind breaker. As for scent control, it seems to work the first few times I've used it but it looses its effectiveness quickly. I like washing my clothes in scent free detergent, shower with a commercial scent free soap and take my chlorophyll. Drying clothing in the fresh air seems to work better than the drier as well. My wife and I also wash our towels along with our hunting clothes...why take a scent free shower and then dry off with a towel that smells of laundry detergent....even the odorless stuff.
