I think the concerns about uv and the need for using scent blocking products are overblown. I personally think care in how you approach a stand and how you set up relative to wind direction is far far more important. Much more interesting from a hunting persepective too, imo. I used to be pretty fanatic about those things, used cover up products andeven peed in a bottle. Now I just wash my clothes with the rest of the laundry and let er fly whenever nature calls. I once had a pretty good size buck come in right after I did it. I think he heard the pattering sound on the leaves and came to investigate. Go figure. Anyway, if it makes you feel better using and worying about all this stuff I say go for it but if you find it to be too much trouble I wouldn't worry about it either. I've hunted both ways and for a lot of years and frankly I just don't see that it makesa noticeabledifference. Killed some pretty nice bucks both ways and seem to see them just as often too.
