This is a particularly hot topic. As the saying goes-you need to hunt the wind. While I do take preventative measures such as you do (showering with special no-scent stuff, washing my clothes in scent free-non UV brightening detergent) as well as bagging my clothes with scent wafers and dressing on-site, I still believe that a deers keen sense of smell will bust you if the wind is blowing your stink in their nostrils.
Here's an example; a buddy that I know wears all of the Scent Lock gear and follows the same measures but also has moaned about getting busted- this after querring him and discovering that he hiked into his spot and was heavily perspiring with no head protection and was hunting out of a ground blind with the wind going in the direction of the deer that he was hunting
These products can help you but are not a cure all for defeating a deers smell. Just my .02. I'm sure that you will get alot of opinions on this one!
